Question

a playground of dimensions 42 m by 32 m needs to be fenced.find the length of fencing required. what will be the cost of fencing at Rs 50 per metre?

Answer 1

Length=42m
Breadth=32 m

Perimeter of rectangle= 2×(L+B)
Perimeter=2×(42+32)=2× 74
Perimeter=148m


So, Length so fencing is 148m.

Cost of fencing at 1 metre=Rs.50
Cost of fencing at 148 metre=50×148
Cost= Rs.7400


So, Total cost of fencing is RS.7400





HOPE IT HELPS YOU!

Answer 2

perimeter of rectangle=2(L+B)
=2(42+32)
=2×74
=148
cost of fencing at rs 50per metre
so =148×50
=7400rs
