Answer:area of the rectangle is 135 cm^2

Perimeter of the rectangle is 48 cm

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
