Question

question 8 of 25
what is the perimeter of the rectangle shown below?
(image of rectangle with a to b labeled 5, a to d labeled 8)
a. 18 units
b. 26 units
c. 13 units
d. 40 units

Explanation:

Step1: Recall perimeter formula for rectangle

The formula for the perimeter \( P \) of a rectangle is \( P = 2\times (length + width) \).

Step2: Identify length and width

From the diagram, the length is \( 8 \) units and the width is \( 5 \) units.

Step3: Substitute values into formula

Substitute \( length = 8 \) and \( width = 5 \) into the formula: \( P = 2\times(8 + 5) \).
First, calculate the sum inside the parentheses: \( 8 + 5 = 13 \).
Then, multiply by 2: \( 2\times13 = 26 \).

Answer:

B. 26 units
