A landscaper places two lengths of wooden garden edging end-to-end to border a flower bed. The first piece is 7127 \frac{1}{2} feet long, and the second piece is 4124 \frac{1}{2} feet long. What is the total length of the edging in inches?

Answer

144
First, the two fractional lengths must be combined: 7127 \frac{1}{2} plus 4124 \frac{1}{2} equals exactly 12 feet. Since there are 12 inches in a single foot, the total measurement in inches is found by multiplying the 12 feet by 12. This yields a final answer of 144 inches.

Step-by-Step Solution

1
Add the lengths of the two pieces of edging together in feet.
712+412=127 \frac{1}{2} + 4 \frac{1}{2} = 12 feet
Finding the total combined length is the first step before converting to the requested unit.
2
Convert the total length from feet to inches.
12×12=14412 \times 12 = 144 inches
There are 12 inches in 1 foot, so multiplying the number of feet by 12 gives the length in inches.

Key Concept

To convert US customary linear measurements from feet to inches, add the fractional lengths to find the total, then multiply the number of feet by 12.
