(3) 144 sq m
(4) 192 sq m​

Answer 1

(3) 144 sq m is the correct answer

as perimeter = 4 × side

side = 48 /4 = 12 m

area = side × side

area = 12 × 12 m^2

area = 144 sq m

SOLUTION :

❒ Given :-

• Perimeter of a square = 48 m

❒ To Find :-

• Area of the square = ?

❒ Required formulas :-

• ❖ Perimeter of a square = 4 × Side

• ❖ Area of a square = Side × Side = (Side)²

❒ Calculation of side of the square :-

We have,

• ★ Perimeter of the square = 48 m

➨ 4 × Side = 48

➨ Side = $\sf{\dfrac{48}{4}}$

➨ Side = 12

∴ Side of the square = 12 m

❒ Calculation of area of the square :-

• ★ Area of the square = (Side)²

➨ Area of the square = (12 m)²

∴ Area of the square = 144 m²

• Hence, the area of the square is 144 sq. m.
