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, \(2\) ft and \(2\) ft.

Step2: Use perimeter formula for irregular shape

Perimeter is the sum of all side - lengths. \(P=(5 + 2)+(7+2 + 2)+5+2\).
First, calculate the sums within parentheses: \((5 + 2)=7\), \((7+2 + 2)=11\).
Then, \(P = 7+11 + 5+2\).
\(P=24\) ft.

Answer:

B. 24 ft
