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

$\begin{gathered} 244=134+2w \\ 2w=244-134 \\ 2w=110 \\ w=\frac{110}{2} \\ w=55 \end{gathered}$

the width is 55 m
