Question

Diana is building a stage, which is shaped like a trapezoid. The bases are 8 and 3.9 yards, and the
height is 20 yards. How many square yards large is the stage?

Answer 1

Answer:

Area of trapezium: 1/2 * (base 1 + base 2) * h

<=> 1/2 * (8 + 3.9) * 20 = 1/2 * 11.9 * 20 = 119 square yards
