Question

The rectangular floor of a classroom is 24 feet in length and 40 feet in width. A scale drawing of the floor has a length of 6 inches. What is the area, in square inches, of the floor in the scale drawing?

Answer 1

60 square inches

Explanation:

Measure of length in scale drawing = Measure of actual length

6 inches = 24 feet

∴ 1 inch =
`(24)/(6)` feet

∴Unit multiplier applied:

∴1 inch in scale drawing = 4 feet of actual measurement

Measure of width in scale drawing = Measure of actual width

x inches = 40 feet

∴ x inches = (40 feet) × (
`(1 inch)/(4 feet)`)

Measure of width in scale drawing = 10 inches

Area of rectangular floor in the scale drawing = (Length) × (Width)

= (6 inches) × (10 inches)

= 60 square inches
