A rectangle is 15 cm long. Find the area and perimeter of the rectangle if its width is 3 5 the length.

Answer:area of the rectangle is 135 cm^2

Perimeter of the rectangle is 48 cm

Step-by-step explanation:

The formula for determining the perimeter of a rectangle is expressed as

Perimeter = 2 (L + W)

Where

L represents the length of the rectangle

W represents the width of the rectangle.

From the information given,

Length of the rectangle = 15cm

Width of the rectangle = 3/5 * 15 = 9 cm. Therefore

Perimeter = 2 (9 + 15) = 2 * 24 = 48 cm

The formula for determining the area of a rectangle is expressed as

Area = LW

Therefore

Area = 15 * 9 = 135 cm^2
