Finding the area of a rectangle: The area of a rectangle is found by multiplying the base times the height.
For example: If a rectangle has a base of length 12 inches and a height of 6 inches, multiply 12*6 to find the area of 72 square inches.
Finding the area of a square is done the same way.
If the square has 10 inch sides, multiply 10*10 to find the area of 100 square inches.
Finding the area of a triangle:
The area of a triangle is found by multiplying the base times the onehalf the height.
For example: If a triangle has a base of length 12 inches and a height of 6 inches, its area is 12*3 to find the area of 36 square inches.
Finding the area of a circle:
To find the area of a circle, multiplying pi ( 3.14) by the square of the radius.
If the radius is 6 inches, multiply 3.14*6*6 to get the area of 113.04 square inches.
Finding the circumference of a circle:
The circumference of a circle is found by multiplying pi (3.14 ) by the diameter of the circle.
For example, if a circle has a 6 inch diameter, multiply 3.14 * 6 to find the 18.84 inch circumference.
