Area of a triangle = 1/2*base*altitude in square units Area = 45 square feet

39 square feet. this is 1/2 * 13 * 6

The base of the triangle is 6 feet

The area (A) of a triangle = 1/2 x base x altitude (or height). Area = 1/2 x 11 x 8 = 44 sq ft

Area of a triangle in square feet = (one half of the length of the base in feet) times (height of the triangle in feet)
