Question
The distance around a rectangle is given by the expression 2(l + w), where l is the length and w is thewidth. What is an equivalent expression for this distance?
Solution
An equivalent expression for the distance around a rectangle, also known as the perimeter, is 2l + 2w. This is because the expression 2(l + w) can be simplified by applying the distributive property of multiplication over addition, which states that 2(l + w) = 2l + 2w.
