Perimeter = 2 × (length + width)

Front

What is the formula for the area of a parallelogram?

Back

Area = base × height

Front

What is the formula for the perimeter of a parallelogram?

Back

Perimeter = 2 × (base + side) where side is the length of the non-parallel sides

Front

What is the formula for the area of a trapezoid?

Back

Area = 1/2 × (base1 + base2) × height
