Q.73 - Algebra 2

Question

Fencing Micah has 74 feet of fencing to make a

dog run in his yard. He wants the length to be 2.5 feet

more than the width. Find the length, L, by solving the

equation 2L + 2(L − 2.5) = 74.

Step-by-Step Solution

Answer

The length of Fencing is $L=19.75$ feet

Step 1 - The given information

$2L + 2(L - 2.5) = 74$

Step 2

$$\begin{gathered} 2L + 2(L - 2.5) = 74 \\ \Rightarrow 2L + 2L - 5 = 74 \\ \Rightarrow 4L=79 \\ \Rightarrow L=79/4 \\ \Rightarrow L=19.75 \end{gathered}$$
