Texts: Can somebody please help me solve these 4 questions? I solved #2, but I am not sure if it's correct. 1. Compute the area of a trapezoid. Area = (1/2) x (base1 + base2) x height. 2. Find the area of a triangle. Area = (1/2) x base x height. Area = (1/2) x 4 x 3. 3. Compute the area of the trapezoid. Area = (base1 + base2) x height. Area = (b + bH). 4. Determine the area of the triangle formed by points A, B, and C. A to B = 7. S A to D = 16.8. B to D = 6.
