A playground has three different playing areas: a square area for a swing set, a rectangular area for a slide, and an area of 30 square feet for a basketball hoop. The following expression represents the total area of a rectangular playground, and x represents side length of the area with the swing set. x^2 + 11x + 30
What does x^2 represent in this expression
In this expression x^2 would represent the area of the square. The area of the square is found by multiplying the length by the width. A square would have the same length for each therefore it can be represented as x^2.
