Area

The length of the base of a parallelogram is 23 centimeters, and the corresponding height is h centimeters. Which formula can be used to find A, the area of the parallelogram in square centimeters?

• A = 23 + h

• A = 23h

• A = ½(23h)

• A = ½(23+h)

The bases of a trapezoid are 10 centimeters and 14 centimeters, and the height is h centimeters. Which equation can be used to represent A, the area of the trapezoid in square centimeters?
