No w i wil l teach .how can fin d area of rectan gle                     so first of all you will k now the field is in rectan g le form so you can find his area i n this metho d  first find   the s ide of rectangle  then use this formula for rectangle ar ea                                                            L x W                         wh ere L is the length of rectangle                                   and                          W is the width of rectan gle so fin d the a of rectangle ? a is the symb ol of area                 putting the value of L and W              10x20                 =30   then giv e h im unit fo r e xamp le you ta king reading in meter             then              30 meter squar     if you have any problem or question then do ask them in comment section below. if you have any problem then you can call me so keep visiting if you have any compl ain so you can call me on th is number from all over the world

F inding areas of different condition of earth.           Earth areas have alot of condition but so me we discuss   l ook the photo s which i s gi vin b el ow CONDITION  OF EARTH AREAS we will discus s t hese are a s of the earth. and i wil l teac h you find ing are as of this condition of the earth so i will solve every ge ometrical shape in one post wi th formulas  so look next post so lve these condition of t he earth    Note: Now if you have any problem or question then do ask them in comment section below. if you have any problem then you can call me so keep visiting

FUNCTION OF STAFF ROD IN Survey STAFF ROD it is the basic instrument for leveling machine . it is made from iron staff rod have inch mm cm symbol .It is also use for horizontal distance it is available is different length . level stuff have 15meter length.due to staff rod level aqua racy is 100percent             

Level  function in survey field simple definition Level machine it is the advance technology of the this generation .Level can find vertical and horizontal distance of the earth fig no :3 level have many types 1.digital level 2.automatic level 3.precise level level work only 100meter parts of level 1.tripod 2.two parallel flate 3.telescope 4.object glass 5.eye piece 6.bubble tube 7. bubble mirror 8. focusing screw 9.leveling screw 10.plumbing fork I will discuss parts in another post with explanation if you have any problem or question then do ask them in comment section below. if you have any problem then you can call me so keep visiting

Chain and its Length and Types chain is a survey instrument.which is use for land survey , It,s accuracy is not 100 percent it is old method chain is available in different type many types given below it is made from iron two links connect with a ring both edge of chain is include of handle. Chain and its Length and Types                                  Types of chian. Metric chain Steel band chai Günter’s Chain Revenue Chain Engineers chain 1.Engineering chain engineering chain have 100ft and 100 links so one link is equal to one feet. it is use for land survey .this method is very old method and it,s accuracy is very less and it is use for big areas 2.Gunter chain Gunter chain have 66 ft and 100 links so one link is equal 0.66ft .it is also for land survey. after 10 links in the chain have a talley. it,s aquracy is also very less. 3

Tape function in survey  Surveyor's tape is a product designed for use by surveyors in the field. surveyor's tape is not a tape in the sense of an adhesive, this is survey tape instrument .which is use for land servey.it is inexpensive method of survey.it is use for plan survey .tape have many length. it can use every one for measurement.                                                                 fig no:1 t have inch feet cm and mm symbol.which can easily find length of every thing Surveying is an product of science which involves measuring distances, boundaries, and the relationship between locations. It is used to collect data , ranging from the pitch of a proposed road site to the depth of the sea river canal ocean. Surveying is often employed to determine accurate property lines, prepare a site for construction, or to measure areas under scrutinys, such as forests which are about to be logged. Surveyors use a variety of equipment to measure and mark
