i hope it helps u...
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
