Answer 2

Answer:

Given :-

Perimeter of the square = 96 cm

To Find :-

The area of the square

Solution :-

We know that,

Perimeter of a square = 4 × side

On inserting the values in the formula

We get ,

96 cm = 4 × side

$\implies\: side\: =\: {\bold{\dfrac{96}{4}}}$

=> side = 24

Therefore, measure of a side of the given square is 24 cm

Area of a square = side²

On inserting the values in the formula

We get ,

Area of the square = (24 cm)²

= 24 cm × 24 cm

= 576 cm²

Therefore, area of the given square is 576 cm²
