The answer is 60. The formula for finding the area of a trapezoid or trapezium (UK) is \(A= \frac{1}{2} (base1+base2)(height)\) Base1 and base2 can be either 8 or 12 and the height is 6. \(A= \frac{1}{2} (8+12)(6)\) Then Solve for parenthesis first. \(A= \frac{1}{2} (20)(6)\) Then multiply to get the answer. \(A= (10)(6)\) Answer: \(A= 60\)
