Question

find the area of a square park whose perimeter is 4.8m

Answer 1

$perimeter \: = > 4.8m \\ 4a = 4.8 \\ a = \frac{4.8}{4} \\ a = 1.2 \\ area = {a}^{2} \\ = > {1.2}^{2} \\ = > 1.2 \times 1.2 \\ = > 1.44sq \: m$

Answer 2

Let the side of square be x

Perimeter of square = 4×Side

= 4.8 = 4×x

= 4.8 = 4x

= 4.8 / 4 =x

= 1.2

Area of square = Side ×Side

= (1.2×1.2)m

= 1.44 m²
