A section of a deck is shaped like a trapezoid. For this section, the length of one base is 23 feet, and the length of the other base is 42 feet. The height is 30 feet. What is the area of this section of the deck?
Since the formula for a trapezoid is A=(1/2)(h)(b1+b2) Replace them with A=(1/2)(30)(23+42)multiply them all but add 23+42 first. Then you will have your answer:975 feet^2
