Question

if area of square is 30 cm find perimeter of square

Answer 1

30cm but cause all sides of square is equal

Answer 2

The perimeter of a square is  4√30 cm

Explanation:

Given:

1. Area of a square = 30 cm²

To find:

The perimeter of a square

Formula:

The Area of the square = a²

The Perimeter of the square = 4a

Solution:

==>  Area = 30 cm²

==> Apply the value in the formula

==> Area = a²

==> a = side of the square

==> Square four sides are equal

==> 30 = a²

==> Taking square root on both sides

==> √30 = √a²

==> a = √30

==> a = $\sqrt{3\times5\times2}$

==> a = √30 cm

==> The side of a square is √30 cm

==> Apply a value in the perimeter formula

==> Perimeter = 4a

==> Perimeter = 4(√30)

==> Perimeter = 4√30 cm

==> The perimeter of a square is  4√30 cm
