Answer 2

❍ Question -:

The perimeter of a square is 4 times length of its side. The perimeter of a square is 18 cm more than the length of its side, find the length and the perimeter.

❍ Explanation -:

In this question we are provided that the perimeter of a square is 4 times the length of its side.It is also given that the perimeter is 18 cm more than the length. We are asked to calculate the length and perimeter.

First we will form an equation

Let us assume the length as x.

Then,

Perimeter = 4x

Perimeter = x + 18

Let us solve this equation

$\small\sf{ 4x = x + 18}$

Subtract

$\small\sf {4x - x = 18}$

$\small\sf{3x = 18}$

Divide

$\small\sf{x = \dfrac{18}{3} = 6 }$

$\small \underline{\boxed{ \rm{ Length = 6 cm}}}$

$\small \underline{ \boxed{\rm{ Perimeter = 6 + 18 = 24 cm }}}$
