Answer:
The area of the actual wall is 693 square feet.
Step-by-step explanation:
Step 1 : Finding the length of the wall in feet.
Length of the wall in the scale drawing = 28 inches
Length of the actual wall = [tex]28 \times \frac{3}{2}[/tex] feet
Length of the actual wall = [tex]\frac{84}{2}[/tex] feet
Length of the actual wall = 42 feet
Step 2 : Finding the width of the wall in feet.
Width of the wall in the scale drawing = 11 inches
Width of the actual wall = [tex]11 \times \frac{3}{2}[/tex] feet
Width of the actual wall = [tex]\frac{33}{2}[/tex] feet
Width of the actual wall = 16.5 feet
Step 3 :
Find area of the wall in square feet.
Area of the actual wall = Length x Width
Area of the actual wall = 42 x 16.5
Area of the actual wall = 693 square feet.
