### Grade 5 - Mathematics8.6 Finding the Area/Perimeter of Triangles

 If a triangle has a base b units and height of h units, then The area A is 1/2 base x height. The perimeter is the sum of lengths of all the three sides side1 + side2 + side3. A = 1/2 (b x h) P = a + b + c Example: A triangle has a base of 3 ft and height of 5 ft. Find the area of the triangle. Area of triangle = (b x h) / 2 Substituting the values b = 3 and height = 5 (3 x 5)/2 = 15/2 Answer: 7.5 square feet Note: The units of area are square feet or ft2. Directions: Find the area for the following questions. Also write at least 5 examples of your own.
