Question

A path of width 10 m runs along the outside of square park of side 100 m. Find the area

of the path. Also, find the cost of cementing the path at the rate of Rs 200 per 10 sq. m ?​

Answer 1

Step-by-step explanation:

Answer

Given inner side of square park, s=100 cm

Area of inner square =100

2

=10000 cm

2

width of path,w=5 cm

Outer side of square =100+5+5=110 cm

Area of outer square =110

2

=12100 cm

2

Area of path =12100−10000=2100 cm

2

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