Answer:

  • See below

Step-by-step explanation:

A)

According to dimensions of the garage, the scale is:

  • 1 in : 20 ft, as the width of the garage is 20 ft and on paper is 1 in

B)

Living room

Dimensions on paper:

  • 2 in x 1 1/4 in

C)

Actual dimensions:

  • 2*20 ft = 40 ft and
  • 1 1/4 * 20 ft = 25 ft

D)

The area of the living room:

  • A = lw = 25*40 = 1000 ft²

Cost of carpet:

  • 1000*$1.25 = $1250

Length

  • 20(2)=40ft

Width

  • 1.25(20)
  • 25ft

Area

  • 25(40)
  • 1000ft²

Total cost

  • 1000(1.25)
  • $1250
