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 \(l = 7\) m and the width \(w=4\) 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:

\(22\)
