Question

The Perimeter of a rectangle is 304 cm. The length is 40 cm longer than the width. Find the length and width.

Answer 1

96,56

Explanation:

Perimeter = 2(length) + 2(width)

width=x

304=2x+2(x+40)

304=4x+80

224=4x

x=56

lenght=56+40

=96

width=56 cm

lenght=96cm

Answer 2

Explanation:

Perimeter = 2(length) + 2(width)

let x represent the width

`304 = 2x + 2(x + 40)`

`304 = 4x + 80`

`224 = 4x`

`x = 56`

this means that the width is 56cm

sub this into the length:

length = 56 + 40

= 96cm
