Finding Areas

Calculating the Area of a Square

How to find the area of a square:

• The area of a square can be found by multiplying the base times itself. This is similar to the area of a rectangle but the base is the same length as the height.
• If a square has a base of length 6 inches its area is 6*6=36 square inches

Calculating the Area of a Rectangle

How to find the area of a rectangle:

• The area of a rectangle can be found by multiplying the base times the height.
• If a rectangle has a base of length 6 inches and a height of 4 inches, its area is 6*4=24 square inches

Calculating the Area of a Parallelogram

How to find the area of a parallelogram:

• The area of a parallelogram can be found by multiplying the base times the height.
• If a parallelogram has a base of length 6 inches and a height of 4 inches, its area is 6*4=24 square inches

Calculating the Area of a Trapezoid

A trapezoid is a quadrilateral (has 4 sides) and has only one pair of sides parallel.

How to determine the area of a trapezoid:

• Add the lengths of the 2 parallel sides
• divide by 2 to get the average length of the parallel sides.
• Multiply this by the height (distance between the parallel sides

Calculating the Area of a Triangle

How to find the area of a triangle:

• The area of a triangle can be found by multiplying the base times the one-half the height.
• If a triangle has a base of length 6 inches and a height of 4 inches, its area is 6*2=12 square inches

Finding the Area of a Circle

How to find the area of a circle:

• The area of a circle can be found by multiplying pi ( π = 3.14) by the square of the radius
• If a circle has a radius of 4, its area is 3.14*4*4=50.24
• If you know the diameter, the radius is 1/2 as large.
