Question

Find the perimeter of a square that has a side that is 4.5 meters long.A. 4.5 metersB. 9 metersC. 13.5 metersD. 18 meters

Answer 1

The square has all four sides equal therefore the perimeter is four times the length of any side of the square.

`P=4L`

In this case, we have that all four sides are equal to 4.5. Then, L=4.5.

Using the perimeter formula:

`P=4(4.5meters)`
`P=18\text{meters}`

Hence, the perimeter is equal to 18 meters. The correct answer is

option D.
