Question

find the perimeter of the rectangle. include the unit. 21 m 29 m

Explanation:

Step1: Recall the formula for the perimeter of a rectangle

The formula for the perimeter \( P \) of a rectangle is \( P = 2\times(\text{length}+\text{width}) \). Here, the length \( l = 29\space m \) and the width \( w = 21\space m \).

Step2: Substitute the values into the formula

Substitute \( l = 29\) and \( w = 21 \) into \( P = 2\times(l + w) \). So, \( P=2\times(29 + 21) \).
First, calculate the sum inside the parentheses: \( 29+21=50 \). Then, multiply by 2: \( 2\times50 = 100 \).

Answer:

\( 100\space m \)
