Answer 2

GIVEN:

• Area of square = 49 cm²

TO FIND:

• What is the perimeter of the square ?

SOLUTION:

Let the side of the square be 'a' cm

☞ Firstly, We have to find the side of the square

We know that the formula for finding the area of the square is:-

$\large\bf{\star \: Area = (side)^2 \: \star}$

According to question:-

On putting the given values in the formula, we get

$\sf{\dashrightarrow a^2 = 49 }$

$\sf{\dashrightarrow a = \sqrt{49} }$

$\large\bf{\dashrightarrow \star \: a = 7 \: cm \: \star}$

❝ The side of the square is 7 cm. ❞

☞ Now, we have to find the perimeter of the square

To find the perimeter of the square, we use the formula

$\large\bf{\star \: Perimeter = 4 \times side \: \star}$

On putting the values in the formula, we get

$\sf{\dashrightarrow Perimeter = 4 \times 7 }$

$\large\bf{\dashrightarrow \star \: Perimeter = 28 \: cm \: \star }$

❝ Hence, the perimeter of the square is 28 cm. ❞
