Question
A square park has 40 m as its perimeter. What is the length of its side? Also find its area
Advertisements
Solution
Given perimeter = 40 m
Perimeter of a square = 4 × Length of a side
40 = 4 × Length of a side
∴ Length of its side = `40/4` m
= 10 m
∴ Side of the park = 10 m
Area of a square = (side × side) unit2
= (10 × 10) m2
= 100 m2
∴ Area of the Park = 100 m2
