The perimeter of a square can be found by using the formula
P = 43. If the perimeter of a
square is 72 units and the side
length is 2x – 4, write an
equation and solve for X.

Perimeter of a square = 4 × side

Perimeter of this square = 72 units

Length of each side of this square =

To find the length of each side we can use this equation :-

Using this we can find the length of each side .

Length of each side :-

= 2x - 4

= 2 × 11 - 4

= 22 - 4

= 18

Hence the length of each side = 18

Which means :-

Perimeter of this square :

= 4 × 18

= 72
