Question

The length of a rectangle is twice its width. find the area if its perimiter is 7 1/3 cm

Answer 1

Area = 2.99 cm2

Explanation:

`P=2l+2w`

If:

`l=2w\\P=7(1)/(3) cm=(22)/(3) cm`

Then

`(22)/(3) =2(2w)+2w`

`(22)/(3) =6w`

`(22)/(18) =w`

`l=2w=2((22)/(18) )=(44)/(18)`

lenght simplified=22/9

width simplified = 11/9

Area.

`A=lw=((22)/(9) )((11)/(9) )=((242)/(81) )=2.99cm^(2)`

Hope this helps
