Question

find the perimeter. 7 m 4 m p =? m

Explanation:

Step1: Recall the formula for the perimeter of a rectangle

The formula for the perimeter \( P \) of a rectangle is \( P=2\times(\text{length}+\text{width}) \). Let the length \( l = 7\space m \) and the width \( w = 4\space m \).

Step2: Substitute the values into the formula

Substitute \( l = 7\) and \( w = 4 \) into \( P = 2\times(l + w) \). So \( P=2\times(7 + 4) \).
First, calculate the sum inside the parentheses: \( 7+4=11 \). Then multiply by 2: \( P = 2\times11\).

Answer:

\( 22 \)
