Question

The perimeter of a rectangular field is 244 m. If the length of the field is 67 m, what is it's width?

Answer 1

We have the formula of the perimeter of a rectangle

`P=2l+2w`

where

l=length

w=width

we substitute the values

`244=2(67)+2w`

then we clear w

`\begin{gathered} 244=134+2w \\ 2w=244-134 \\ 2w=110 \\ w=(110)/(2) \\ w=55 \end{gathered}`

the width is 55 m
