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 = feet
Length of the actual wall = 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 = feet
Width of the actual wall = 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.
