Question

what is the perimeter of this rectangle? 3.7 in 6.8 in blank inches submit work it out

Explanation:

Step1: Recall the perimeter formula for a rectangle

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

Step2: Identify the length and width

From the diagram, the length \( l = 6.8 \) in and the width \( w = 3.7 \) in.

Step3: Substitute the values into the formula

First, calculate the sum of length and width: \( l + w = 6.8 + 3.7 = 10.5 \) in.
Then, multiply by 2 to get the perimeter: \( P = 2\times10.5 = 21 \) in.
