Area and Perimeter By Christine Berg Edited by V T Hamilton
Perimeter The sum of the lengths of all sides of the figure
Area The number of square units inside a figure
Area Abbreviations: A = Area b = base h = height
Rectangle To find the area multiply the length of the base times the height
Rectangle A = bh
Parallelogram Draw a rectangle on graph paper. Cut off a triangle on one side and add it to the other. 1 23
Parallelogram The rectangle becomes a parallelogram so the formula is the same as for a rectangle
Triangle The area of a triangle is one half of the length of the base times the height
Triangle 4in Area of the square is 4 times 4 or 16 sq. in. Area of the triangle is one-half 16, or 8 sq.in. A = 1/2 bh A = 1/2 (4)(4) A = 8 sq. in.
