Question

1. the sidewalk from the driveway to camerons house has the dimensions shown below. what is the perimeter of the sidewalk? a. 35 ft b. 24 ft c. 21 ft d. 20 ft

Explanation:

Step1: Identify side - lengths

The horizontal side - lengths are \(5\) ft and \(2\) ft. The vertical side - lengths are \(7\) ft and \(2\) ft. By using the property of perimeter (sum of all side - lengths), we note that the figure can be thought of in terms of its outer - most side lengths.

Step2: Calculate perimeter

The perimeter \(P\) of the figure is \(P=(7 + 2)+(5)+(2)+(2)+(7)+(2)\)
\[

$$\begin{align*} P&=9 + 5+2 + 2+7+2\\ &=27+ 3\\ &=24\text{ ft} \end{align*}$$

\]

Answer:

B. 24 ft
