The width of a rectangle is 2 cm longer than its length. Identify the polynomial that represents the area of the rectangle, and its area when the length is 5 cm.

Sagot :

The area of the rectangle will be 35cm²

Area of a rectangle

The formula for calculating the area of a rectangle is expressed as:

A = lw

If the width of a rectangle is 2 cm longer than its length, then;

w = l + 2

Substitute the given values into the formula:

A = l(l+2)

A = l² + 2l

Given the following parameters:

l = 5cm

A = (5)² + 2(5)

A = 25 + 10

A = 35cm

Hence the area of the rectangle will be 35cm²
