Question

A square lawn area is 62500 sq metre A wooden fence is to be laid around lawn. How long wooden fance is required?what will be its cost at the rate of Rs 50 per metre

Answer 1

Area of square lawn = 62500 sq meter

if side = a

=> a^2 = 62500

=> a = √62500

=> a = 250m

perimeter = 4a = 4 × 250 = 1000m

Cost = 1000 × 50 = ₹50,000

Answer 2

Area=62500 m*2
Let the side be x
ATQ,
62500=x*2
=(62500) *1/2=x
x=250 m
Perimeter(required fencing)=250*4=1000 m
Cost of fencing=1000*₹50=₹50000
