Question

A path 5m wide runs along outside a square park of side 90m. Find : a) Area of path. b) The cost of cementing it at the rate of Rs 150 per m 2 .​

Answer 1

Answer:a)Area of path is 1900 $m^{2}$ .

b) The cost of cementing it at the rate of Rs 150 per m2 is  Rs. 285000 .

Step-by-step explanation:

a)

Given inner side of square park, s=90 m

Area of inner square = $90^{2} = 8100 m^{2}$  

width of path,w=5 m

Outer side of square =5+90+5=100 m

Area of outer square =$100^{2}= 10000 m^{2}$

Area of path =10000 - 8100 = 1900 $m^{2}$

b)

Cost of cementing at the rate of Rs 150 per sq m =  1900 X 150 = Rs 285000
