Question

A lady developed a square park for children. She spent Rs176400 on the development of the park at rate of Rs25 per square metre. Find the cost of fencing of the park at rupees 15 per metre.

Answer 1

hello.

here is your answer,

total money spent = 176400 rs

cost of per sq. meter = 25 rs

Total area = 176400/25

= 7056 m^2

area of sq. = side^2 = s ^2

s^2 = 7056m^2

side = √7056

side= 84m

perimeter = 4 * 84

= 336 m

cost of fencing = 15/m

total cost of fencing = 336*15

= 5040 rs
