Question

The perimeter of a rectangle is 24 meters. If the length of the rectangle is 8 meters, what is thewidth (in meters)?8Submit Answer

Answer 1

We have the next formula for the perimeter of a rectangle

`P=2l+2w`

where l is the length and w is the width

in our case

P=24m

l=8m

w=?

we substitute the values

`24=2(8)+2w`

we simplify the expression

`24=16+2w`

then we isolate the w

`\begin{gathered} 2w=24-16 \\ 2w=8 \\ w=(8)/(2) \\ w=4 \end{gathered}`

The width is 4 m
