Question

1. the length of a car on a scale drawing is 3 inches. if the scale drawing has a scale of 1 inch = 2.5 ft, what is the actual length of the car? 2. what is the actual height of the door? scale: 1 in. = 2.5 ft. so the actual length of the swimming pool is 15 meters. 1/3 5 = x/5 5 15 = x

Explanation:

Step1: Identify the scale - ratio

The scale is 1 in. = 2.5 ft.

Step2: Set up a proportion

Let the actual length of the car be $x$ feet. The length on the scale - drawing is 2.5 inches. We set up the proportion $\frac{1\text{ in}}{2.5\text{ ft}}=\frac{2.5\text{ in}}{x\text{ ft}}$.

Step3: Cross - multiply

Cross - multiplying gives us $1\times x = 2.5\times2.5$.

Step4: Solve for $x$

$x = 6.25$ feet.

Answer:

6.25 feet
