Question

A rectangle has one side that measures m + 5. The other side measures 2. Write an

expression to represent the perimeter of the rectangle.

Answer 1

Answer: 2m + 14

Explanation:

Perimeter is the sum of all the sides.

A rectangle has 2 pairs of equal sides, so one way to write the expression would be 2(m + 5) + 2(2).

Distributing the 2s, leaves 2m + 10 + 4

Combine like terms, and you have 2m + 14.

Hope this helps!
