21 8x 4x + 4
Expert Answer
Length of the entire door = 8x
Width of the entire door = 4x+4
Area of the entire door = length * width
= (8x)*(4x+4)
We need to apply the distributive property
a*(b+c) = a*b+a*c
So, Area of the entire door is shown on the board
Length of the cut out portion of the door = 2x
Width of the cut out portion of the door = x
Area of the cut out portion of the door = length * width
= (2x)*(x)
= 2x²
Area of the surface on the front face of the door that needs to be stained is calculated as shown on the board
