Question

The perimeter of a rectangle is 28.8 cm. The length of the rectangle is twice as long as the width. Find the length and width of the rectangle

Answer 1

the length is 9.6cm

and the width is 4.8cm

Explanation:

2 length

1 width

Since there are two of each...

there are a total of 6

6x=28.8

x=4.8

Therefore the length is 9.6cm

and the width is 4.8cm

Answer 2

`Length=9.34 cm\\\\Width=4.67 cm`

Explanation:

Perimeter of the rectangle is the sum of all its four sides that can be find by:

`Perimeter=2(Length+Width)`

Length=2*Width

For, Perimeter=28.8 cm

`28=2(2*Width+Width)\\\\28=2*(2W+W)\\\\28=2(3W)\\\\3W=28/2\\\\3W=14\\\\W=14/3\\\\W=4.67 cm\\\\length=2*Width\\\\=4.67*2\\\\=9.34 cm\\\\`

`Length=9.34 cm\\\\Width=4.67 cm`
