Marlene is buying a new plasma television. The height of the screen of the television is the width plus 5 inches. Write the equation for the area and the perimeter.

Step-by-step explanation:

The plasma television is first of all a rectangle.

The formula for the area of a rectangle is 1/2(w*h)

Where w = width

H = height

The formula for perimeter = 2(h+w)

1. For area:

Height = h = w+5

Width = w

Inserting into formula

1/2((w+h)*w)

= 1/2(w²+wh)

This is the equation for the area

2. The perimeter:

The formula = 2(h+w)

= 2[(w+5)+w]

This is the equation for the perimeter
