    perimeter means to add up all the lengths (sides) of the triangle... so find the total of all the sides. Area of a triangle = 1/2 * base * height Looking at your diagram, the base = 6 and height = 2.5 Plug base = 6 and height = 2.5 into the area of a triangle formula and we get: Area of triangle = 1/2 * 6 * 2.5 = ?

    well... perimeter = total of all the lengths. So add all three sides and what do you get?
