Area = length x width. A rectangle 8m x 5m has area 40 square metres.
Area = 0.5 x base x height. Height must be perpendicular to the base.
Area = pi x radius squared. For radius 7: area = 3.14159 x 49 = 153.94 square units.
Area = 0.5 x (side a + side b) x height, where a and b are the two parallel sides.
Area = pi x a x b, where a and b are the two semi-axes.
Area is the 2D space inside a shape measured in square units. Perimeter is the distance around the edge in linear units.
1 square metre = 10.764 square feet. Multiply by 10.764 to convert.
Divide into known shapes, calculate each area separately, then add them together.
