Quadratic Equations Area Problems

The area of a playground is 336 yd2 . The width of the playground is 5 yd longer than its length. Find the length and width of the playground

•  length = 26 yd, width = 21 yd
• length = 21 yd, width = 26 yd 
• length = 21 yd, width = 16 yd 
• length = 16 yd, width = 21 yd

The length of a rectangle is 2 units more than the height.

Given the perimeter is 80, which equation below is correct

• x + (x+2) = 80

• x - (x+2) = 80

• 2(x + (x+2)) = 80

• 2(x - (x+2)) = 80
