Chapter 4, Problem 4SAP

To determine

To find:.equation that could be used to find s, the shorter side of the garden.

Answer to Problem 4SAP

E. $2\left(s+6\right)+2s=60$

Explanation of Solution

Given information: A rectangular garden is surrounded by a 60 foot long fence. One side of the garden is 6 feet longer than the other.

A. $8s+5=60$

B. $4s=60+12$

C. $s\left(s+6\right)-6=60$

D. $2\left(s-6\right)+2s=60$

E. $2\left(s+6\right)+2s=60$

Calculation:

Let  s  represents the shorter side, then the longer side;

  $\begin{array}{l}2\left[s+\left(s+6\right)\right]=60\\ 2\left(s+6\right)+2s=60\end{array}$ is  s + 6 .

Since the perimeter is 60 foot, so equation would be

So the correct answer is E.
