Question

diagram of classroom floor
1.5 in.
2 in.
what is the area, in square feet, of the actual classroom?

Explanation:

Step1: Find the scale - factor

The scale is 1 in. represents 14 feet.

Step2: Find the actual length and width

The length on the drawing is $l_d = 2$ in., so the actual length $l_a=2\times14 = 28$ feet. The width on the drawing is $w_d = 1.5$ in., so the actual width $w_a=1.5\times14 = 21$ feet.

Step3: Calculate the area of the actual classroom

The area of a rectangle is $A = l\times w$. So $A=28\times21=588$ square feet.

Answer:

588 square feet
