2. Area Formulas Square - The area of a square is the square of
the length of a side.
Rectangle - The area of a rectangle is the product
of its base and height
Parallelogram - The area of a parallelogram is the product of
a base and its corresponding height
Triangle - The area of a triangle is one half the product of a
base and its corresponding height
