Question

A path of 2.5 m wide run along outside a square path of side 65 m find the area of the path​

Answer 1

Answer:

5200

Step-by-step explanation:

Given inner side of square park, s=100 cm 

Area of inner square =1002=10000 cm2

width of path,w=5 cm

Outer side of square =100+5+5=110 cm 

Area of outer square =1102=12100 cm2 

Area of path =12100−10000=2100 cm2

Cost of cementing at the rate of Rs 250 per 10 sq cm = Rs 250×210= Rs 52500

∴ Cost of cementing a 2100 cm2 path =Rs. 52500
