Question

A path is 5 metre bind a long inside the run along inside the inside the square Park hundred metre square find the area of cementing it at the rate of hundred metre square per metre square

Answer 1

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

∴ Cost of cementing a 2100 cm

2

path =Rs. 52500
