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

Answer:

$Length=9.34 cm\\\\Width=4.67 cm$

Step-by-step 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

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

$Length=9.34 cm\\\\Width=4.67 cm$

Answer 2

Answer:

the length is 9.6cm

and the width is 4.8cm

Step-by-step 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
