Question

A garden is 120 m long and 80 m board .In the middle of there is a circular tank of radius 14 m . Find the cost of turfing the remaining portion of the garden at rate of $ 1.20 per square meters

Answer 1

Step-by-step explanation:

Length of garden=120 m

Breadth of garden=80 m

Therefore,

Area of garden=(120×80)m^2

=9600m^2

Radius of tank=14 m

Therefore,

Area of tank= pi×(14)^2 m^2

=(22×28)m^2

=616 m^2

Remaining area of garden=(9600-616)m^2

=8984 m^2

Therefore,

cost of turfing= rs(8984×1.20)

=rs 10,780.20
