The area of the playground is y² - 2y - 8
Area of a rectangle is expressed as:
Area of the rectangle = LW
Given
L is the length = y + 2
W is the width = y - 4
Substitute the given expression into the formula
A = (y+2)(y-4)
A = y² - 4y + 2y - 8
A = y² - 2y - 8
Hence the area of the playground is y² - 2y - 8
