length

20 m

7 steps

Let width be $w$ m.
Then length is $(w + 10)$ m.

Formula for perimeter of rectangle:
$P = 2(l + w)$
Substitute values.
$60 = 2((w + 10) + w)$
Simplify inside parentheses first.
$60 = 2(2w + 10)$
Divide both sides by 2.
$30 = 2w + 10$
Subtract 10 from both sides.
$20 = 2w$
Divide both sides by 2.
$w = 10$
Find length.
$l = w + 10 = 10 + 10 = 20$
**Final answer: Width = 10 m, length = 20 m}
