Question

find the area of a square whose perimeter is 440m. Also, find the cost of growing grass on it at the rate of @2.15 per square m

Answer 1

perimeter of square=440m
each side=449/4=110m
area=110^2=12100m^2
cost of growing grass=₹(12100×2.15)=₹26015

Answer 2

Heya,

Perimeter = 440m

Perimeter = 4a
440 = 4a
440/4 = a
110 = a

Area = a^2
Area = 110 × 110
Area = 12,100 m^2

Cost of growing grass = Area × 2.15
Cost of growing grass = 12,100 × 2.15
Cost of growing grass = Rs.26,015

Hope my answer helps you :)
