Answer:
length: 38 feet
width: 10 feet
area: 380 ft²
Explanation:
The scale between the drawing and the actual studio is 2 in : 5 ft. If we divide both sides by 2, we find that the scale is 1 in : 2.5 feet.
For the first number, 15.2 inches, if we multiply it by 2.5 and change the label to "feet", we can find the real length.
15.2 * 2.5 = 38.
The length is 38 feet.
For the width, do the same thing.
4 * 2.5 = 10
The width is 10 feet.
Area is length times width. So if we plug in the numbers we just found:
38 * 10 = 380.
The area is 380 ft²
