Question

The length of a rectangle is 3 more than its width. The perimeter of the rectangle is 58 cm. What are the rectangle's dimensions?

Answer 1

13 cm and 16 cm

Explanation:

Let the width be `x` and length be `(x+3)`.
now, we have,
`Perimeter=2(l+w)`
`58 cm=2(x+x+3)`
`4x+6=58 cm`
`4x=52 cm`
`x=52/4 cm`
`:. x=13 cm`
So, width = `x` =13 cm
and, length = `x+3` = 13 cm +3 =16 cm
