Let's go over these formulas one more time.
Formulas for different shapes:
Area of Rectangle = Base x Height
Area of Triangle = ½(Base × Height)
Area of Parallelogram = Base × Height
Area of Trapezoid = ½(Base_{1} + Base_{2}) × Height
Area of Circle = πr^{2}
Area of a Parallelogram
Area of a Triangle
Area of a Trapezoid
Area of a Circle
Area of a Regular Polygon
a = apothem P = perimeter
