Question

The width of a rectangle is 4 times its length, /. Which expressions represent the perimeter of the rectangle?

Answer 1

Answer:

$P = 10l$

Step-by-step explanation:

Let $w =$ width of rectangle, $l =$ length of rectangle

$P$ = $2l + 2w$

$\because$ $w = 4$×$l$

$\therefore$ $P$ = $2l$ + $2(4l)$

= $2l + 8l$

= $10l$

Hope this helps :)
