Question

(a) The perimeter of a rectangular field is 328 m.If the length of the field is 95 m, what is its width?Width of the field:

Answer 1

The rule of the perimeter of a rectangle is

$P=2(L+W)$

L is the length

W is the width

Since the length of the field is 95 m

The perimeter of the field is 328 m

Substitute them in the rule

$2(95+W)=328$

Divide both sides by 2

$95+W=164$

Subtract 95 from both sides

$\begin{gathered} 95-95+W=164-95 \\ W=69 \end{gathered}$

The width of the field is 69 m
