Question

a scale drawing of a rectangular bedroom is shown below. using a scale of 1 cm = 4 feet, enter the actual area of the bedroom in square feet.
3.5 cm
2.5 cm
blank ft.²
enter your answer as the correct value, like this: 42

Explanation:

Step1: Calculate the actual length

Since the scale is \(1\ cm = 4\) feet, for the length of \(3.5\ cm\) in the drawing, the actual length \(L\) is \(L=3.5\times4 = 14\) feet.

Step2: Calculate the actual width

For the width of \(2.5\ cm\) in the drawing, the actual width \(W\) is \(W = 2.5\times4=10\) feet.

Step3: Calculate the area of the rectangle

The area formula of a rectangle is \(A = L\times W\). Substitute \(L = 14\) and \(W = 10\) into the formula, we get \(A=14\times10=140\) square - feet.

Answer:

140
