Questions: Find the actual length of the car. The car length is □ feet. (Round to the nearest tenth.)

Solution Steps

The drawing shows that 7 inches on the drawing represents 2.7 inches of the actual car width. So the scale is:

Scale = (Actual width) / (Drawing width) = 2.7 inches / 7 inches = 0.3857

From the first picture, the length of the car in the drawing is marked with a question mark. We are given that the length of the car in the drawing is made up of two segments, one is "?" and the other is 5.7 inches. The total length of "?" and 5.7 inches is equal to 7 inches. So, "?" = 7 inches - 5.7 inches = 1.3 inches. The question mark represents the length of the car's hood. Then, the total length of the car in the drawing is 1.3 inches + 5.7 inches = 7 inches.

Actual length = Drawing length × (Actual width / Drawing width) Actual length = 7 inches × (2.7 inches / 7 inches) = 2.7 inches Actual length = 2.7 inches / 12 inches/foot = 0.225 feet Actual length ≈ 0.2 feet (Rounded to nearest tenth)
