Question

Find the area of a square Park whose perimeter 440 metre also find the cost of growing grass on it at the rate of rupee 2.15 per square metre

Answer 1

perimeter =440
side=440/4=110
area of square=side^2 =110^2 =12100
12100×2.15=121×215
=26015

Answer 2

Solution:

Perimeter = 440 m
Length = P/4 = 440/4 = 110 m
Area = l^2 = 110^2 =12100 m^2
now ,
cost for it = 12100x2.15 =Rs 26015
