Area Calculations:
Use the following formulas to determine area:
• How to determine the area of a CIRCLE:
Multiply pi ( = 3.14) by the square of the radius, If you know the diameter, the radius is 1/2 of the diameter.
• How to determine the area of a RECTANGLE or PARALLELOGRAM:
Multiply the base times the height.
• How to determine the area of a TRIANGLE:
Multiply the base times one-half the height.
• 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)
