Question

The cost of cultivating a rectangular feild at the rate of rs.23 per meter square meter is rs.13,248. If the breadth of the feild is 18m, find the cost of fencing the feild at the rate of 20rs.per meter​

Answer 1

have to find the fencing rate.

rate of cultivation = ₹23/m²

total cost = ₹13248

firstly we have to find the area

= total cost/rate per m²

= 13248/23

= 576m²

then we have to find the Length

area = 576m²

breadth = 18m

length = area/breadth

= 576/18m

= 32m

then we have to find perimeter of field

perimeter = 2(l+b)

= 2(32+18)

= 2×50

= 100m

cost of fencing 1m = ₹20

cost of fencing 100m = ₹20×100

= ₹2000

cost of fencing the field will be ₹2000.

hope it helps.
