Question

Is all of this correct?

Answer 1

Answer: Yes

Explanation:

Hi, to answer this question we have to apply the next formula:

Area of a rectangle (A) = width x lenght

the measures of the front wall before the door was cut:

length: 4 ft

width : 3ft

• A = 3 x 4 = 12 ft2

area of the door ( 2 x2 )

• A = 2 x 2 = 4ft2

The area that Mickey needs to paint is equal to the area of the wall before the cut, minus the area of the door:

• 12-4 = 8 ft2
