Question

The art class is planning to paint a mural on the outside wall this figure is a scale drawing of the wall the scale is 2 inches: 3 feet the scale drawing is 28 inches by 11 inches

Answer 1

The area of the actual wall is 693 square feet.

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 * (3)/(2)` feet

Length of the actual wall =
`(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 * (3)/(2)` feet

Width of the actual wall =
`(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.
