Exercise 26 Page 659

Use the conversion factor that 1 yard is 3 feet.

Converted Lengths: See solution.
Figure's Area: 135 square feet

Practice makes perfect

We want to convert the lengths present on the following diagram to feet. Then, we want to find the area of the figure present on that diagram.

Converting between yards (yd) and feet (ft) will involve using a conversion factor. 3ft/1ydMultiplying the given lengths by this conversion factor will convert it to feet. Let's first convert 5 yards to feet.
5yd * 3ft/1yd
5yd * 3ft/1yd
5yd * 3ft/1yd
5*3ft/1
15ft/1
15ft
5 yards is 15 feet. Now, let's convert 3 yards to feet.
3yd * 3ft/1yd
3yd * 3ft/1yd
3yd * 3ft/1yd
3*3ft/1
9ft/1
9ft
3 yards is 9 feet. Let's replace the lengths on our diagram with their values in feet.

Next, we want to find the area of the figure from the diagram. The figure is a 15 feet by 9 feet rectangle. The area A of a rectangle is the product of its side lengths. Let's find the area of our figure! A = 15( 9)= 135 The figure's area is 135 square feet.
