Answer:
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
