Question

Marshall has a rectangular garden that he wants to enclose with a fence. To calculate the

perimeter, he used the expression below, where represents the width and represents the
length of the garden.
Which other expression could Marshall use to calculate the perimeter?

Answer 1

Explanation:

The expression Marshall used to calculate the perimeter of the rectangular garden is:

Perimeter = 2 * (width + length)

However, there is another equivalent expression that Marshall could use to calculate the perimeter:

Perimeter = 2 * width + 2 * length

Both expressions yield the same result and represent the same concept of adding up all the sides of the rectangular garden to determine its perimeter. The first expression groups the addition of the width and length together before doubling it, while the second expression separately doubles the width and length before adding them together.
