The area of a parallelogram is the same as the area of a square. The base of the parallelogram is twice the length of its height. The side of the square is 2 less than the height of the parallelogram

Area of a parallelogram: a = base • height

Area of a square: a = (side)2

1. variable h = parallelogram height

2. square area + parallelogram area

3. equation: (h – 2)2 + (2h • h)
