Question

A rectangular plot of land is 50 m wide. The cost of fencing the plot at the rate of
18 per metre is 4680. Find
(i) the length of the plot.
(ii) the cost of leveling the plot at the rate of 7.6 per m2.​

Answer 1

Answer:

(i)

Here,

2 ( l+50 ) × 18 = 4680

l+50 = 4680/2×18

l+50 = 130

l = 80m

(ii)

cost of leveling is

l×b×rate

so,

80×50×7.6=3040m²
