Question

what is the perimeter of this rectangle? 8 cm 3 cm 3 cm 8 cm p =? cm

Explanation:

Step1: Recall the formula for the perimeter of a rectangle

The formula for the perimeter of a rectangle is \( P = 2\times(\text{length}+\text{width}) \). Here, the length \( l = 8\) cm and the width \( w = 3\) cm.

Step2: Substitute the values into the formula

Substitute \( l = 8\) and \( w = 3\) into \( P = 2\times(l + w)\). So, \( P=2\times(8 + 3)\).

Step3: Calculate the sum inside the parentheses

First, calculate \(8+3=11\). Then the formula becomes \( P = 2\times11\).

Step4: Perform the multiplication

\(2\times11 = 22\).

Answer:

\(22\)
