The equation a = (b1 + b2) * h / 2 can be used to determine tha area, a, of a trapezoid with height h, and base lengths, b1 and b2. You can find equivalent equations by reanrrangind terms or expanding the parenthesis, using distributive property. These are two equivalent expressions to calculate the same area: 1) a = h * (b1 + b2) / 2; 2) [b1*h + b2*h ] / 2
