Identify Base and Height of Trapezoid

If the bases of a trapezoid are 5 cm and 9 cm, and the height is 4 cm, what is the area of the trapezoid?

• 35 cm²

• 13 cm²

• 28 cm²

• 20 cm²

If the area of a trapezoid is 60 square units and the length of one base is 10 units, what is the length of the other base if the height is 6 units?

• The length of the other base is 8 units.

• The length of the other base is 20 units.

• The length of the other base is 14 units.

• The length of the other base is 5 units.

If the area of a trapezoid is 45 square units and the length of one base is 9 units, what is the length of the other base if the height is 5 units?

• The length of the other base is 6 units

• The length of the other base is 10 units

• The length of the other base is 3 units

• The length of the other base is 8 units

• 8 cm

• 16 cm

• 4 cm

• 12 cm

Answer explanation

To find the height of the trapezoid, use the formula for the area of a trapezoid: Area = (1/2) * (b1 + b2) * h. Plug in the values: 64 = (1/2) * (7 + 9) * h. Solve for h to get h = 8 cm.

Which are the bases?

• 9 and 14

• 13 and 12

• 9 and 13

• 14 and 12

A trapezoid has bases of 6 m and 10 m, and a height of 4 m. Calculate its area.

• 32 m²

• 40 m²

• 64 m²

• 28 m²

A trapezoid has an area of 54 sq. cm. If the height is 6 cm and one of the bases is 12 cm, find the length of the other base.

• 3 cm

• 6 cm

• 9 cm

• 12 cm

A trapezoid has an area of 45 sq. m and a height of 5 m. If one of the bases is 7 m, what is the length of the other base?

• 10 m

• 16 m

• 8 m

• 11 m

Explain how to solve for the lengths of the bases of a trapezoid using the area and the height.

• Area = base1 * base2 * height

• Area = (base1 - base2) * height

• Area = (base1 + base2) / height

• Area = (1/2) * (base1 + base2) * height
