Answer 1

Answer: 55 $\frac{5}{9}$ feet² or 55.556 feet²

Step-by-step explanation:

      The scale means that for ever one in the scale drawing, it is 20 in the actual room. We will convert the dimensions using proportions.

  $\frac{5}{x}=\frac{1}{20}$

  100 = x

-> The length is 100 inches

  $\frac{4}{x}=\frac{1}{20}$

  80 = x

-> The width is 80 inches

    The area of a rectangle can be found by multiplying the length by the width:

A = L * W

A = 100 * 80

A = 8,000 inches²

  To get this into square feet, we will divide by 144. Why? There are 12 inches in a foot. 12 times 12 is 144.

8,000 inches² / 144 = 55 $\frac{5}{9}$ feet²

            The area of the room, in square feet, is 55 $\frac{5}{9}$ feet².
