Question

.The cost of cementing a square courtyard at Rs.137.50 per sq.m is Rs.55000. Find the cost of fencing it at the rate of Rs.27.50 per metre.

Answer 1

Step-by-step explanation:

Cementing a courtyard means finding its area

So,

Area of the Courtyard =

Total cost/cost of cementing per metre

= 55000/137.50

= 400 sq.m

Side of the courtyard =√400 (as its a square)

=20m

Perimeter =20*4=80m

So fencing cost = 27.50*80 rs

= 2200rs
