Perimeter: Area: sum of the side lengths of the figure number of nonoverlapping square units that exactly cover the figure Base (b): Height (h): Can be any side of the triangle Segment from a vertex that forms a right angle with the base

3
HEIGHT (h) may be found: On the triangle Inside the triangle Outside the triangle

Example 1 P = 4s Find the perimeter and area of a square with s = 3.5 in. A = s 2 P = 4(3.5) A = (3.5) 2 P = 14 in. A = 12.25 in 2 Example 2 Find the amount of fabric used to make four rectangles. Each rectangle has a length of in. and a width of in. The area of one triangle is The amount of fabric to make four rectangles is
