Question

find the area of a square park whose perimeter is 440m.also find the cost of growing grass on it at the rate of 2.15 per sq m.

Answer 1

side of park= perimeter/4
440/4
=110 m
area of the park=side*side
110*110
= 12100 m^2
cost of growing grass per m^2=2.15
cost for whole park growing=2.15*110
=236.5

Answer 2

Perimeter = 4 x Side
440m = 4 x Side
Side = 440 / 4
Side = 110m

Area = Side x Side
Area = 110m x 110 m
Area = 12100m2

Therefore ,Area of a square park whose perimeter is 440m is 12100m2

Cost of growing grass on it at the rate of 2.15 per sq m. = RS. 26015
