Answer 1

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   =  $28 \times \frac{3}{2}$ feet

Length  of the  actual wall  =  $\frac{84}{2}$ 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  = $11 \times \frac{3}{2}$ feet

Width of the actual   wall  = $\frac{33}{2}$ 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.
