Question

The perimeter and the ratio of the length to the width of a rectangle are given. Find the length

and width of the rectangle. Then find the area of the rectangle.
7. Length =
7. Perimeter: 36 cm
7:w= 8:1
Width =
Area =

Answer 1

L = 16cm; W = 2cm; Area = 32cm^2

Explanation:

Using the ratio given, we can write down the equation for the perimeter.

36 = 1x + 8x + 1x + 8x

see image.

Then they asked for the area. AREA=length×width

=16×2

=32cm^2
