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)

Analyze Jasper's work. What was his mistake?

The variable should be the length of the square.

The areas of the square and parallelogram are equal.

The area of a square is 4 (h - 2).

The area of a parallelogram is 2h + h.
