Question

The length of a rectangle is 8

meters and the width is 4 meters
Find the perimeter of the
rectangle

Answer 1

24m

Explanation:

l=8m

b=4m=w

p=2(l+b)

p=2(8+4)m

p=2(12m)

p=24m

Answer 2

24 cm

Explanation:

`\boxed{\begin{minipage}{5 cm}\underline{Perimeter of a rectangle} \\\\$P=2(w+l)$\\\\where:\\ \phantom{ww}$\bullet$ $w$ is the width.\\ \phantom{ww}$\bullet$ $l$ is the length. \\\end{minipage}}`

Given values:

• w = 4 m
• l = 8 m

Substitute the given values into the formula:

`\begin{aligned}P&=2(w+l)\\\implies P&=2(4+8)\\&=2(12)\\&=24\;\; \sf cm\end{aligned}`

Therefore, the perimeter of the rectangle is 24 cm.
