Let's start with the scale.
1/2 inch in the drawing represents a real 4 ft.
The drawing is in inches. The real measurement is in ft.
4 divided by 1/2 is 8.
If you multiply the drawing measurements by 8, you get the real measurements in feet.
I assume your drawing measurements are correct.
What is the real measure of the length?
2 1/4 = 2.25
Multiply by 8 to get real feet.
2.25 * 8 = 18
The real length is 18 ft.
What is the real measure of the width?
1 5/8 = 1.625
Multiply by 8 to get real feet.
1.625 * 8 = 13
The real width is 13 ft.
area = length * width = 18 ft * 13 ft = 234 square feet
Answer: D 234 square feet
