Question

Cria wants to measure the perimeter of his bedroom. His bedroom floor is an exact square and one side is 5m. What is the perimeter of his bedroom?

Answer 1

Remember that

The perimeter of a square is given by the formula

`P=4b`

where

b is the length side of the square

In this problem

b=5 m

substitute

`\begin{gathered} P=4*5 \\ P=20\text{ m} \end{gathered}`

The perimeter is 20 meters
