Question

the perimeter of a rectangle can be found using the expression 2l + 2w, where l represents the length and w represents the width. find the perimeter when l = 6 units and w = 4 units.

Explanation:

Step1: Substitute the values of \( l \) and \( w \) into the formula

Given \( l = 6 \) and \( w = 4 \), substitute into \( 2l+2w \). So we have \( 2\times6 + 2\times4 \).

Step2: Calculate each term

First, calculate \( 2\times6=12 \) and \( 2\times4 = 8 \).

Step3: Add the two results

Then add the two results: \( 12 + 8\).
