Question

The total cost of the turfing a rectangular field at rupee 15 per squre meter is 135000. If the lenght of the field is 120 m. Find the its bteadth and perimeter

Answer 1

area of rectangle=l×b
area of rectangle=135000÷15m^2
= 9000m^2
9000m^2=l×b m^2
9000m^2 = 120×b m^2
9000m^2 ÷ 120m^2 = b
75m = b
perimeter=2(l+b)
=2(120+75) m
=2( 195) m
=390m
