Question

A square field has side 150m Long . There is a road 5m wide all around the park outside it . Find the cost of constructing the road at rupees 250 per sq metre

Answer 1

Answer:

let the square feild abcd and the square including the road be pqrs

pq=(150+5)=155

pr=(150+5)=155

abcd=150×150(area of square)

=22500msq

pqrs=155×155

=24025msq

area of road=24025- 22500

=1525msq

cost=1525×250

=Rs.381250
