Area of a trapezoid

Front

What is the formula used to find the area of a trapezoid?

Back

A = (b1 + b2)h / 2, where b1 and b2 are the lengths of the two bases and h is the height.

Front

What do the symbols b1 and b2 represent in the trapezoid area formula?

Back

b1 and b2 represent the lengths of the two parallel sides (bases) of the trapezoid.

Front

What does the height (h) represent in the trapezoid area formula?

Back

The height (h) is the perpendicular distance between the two bases of the trapezoid.

Front

Calculate the area of a trapezoid with bases of 4 ft and 8 ft, and a height of 5 ft.

Back

A = (4 + 8) * 5 / 2 = 30 ft².

Front

If a trapezoid has an area of 50 ft² and a height of 5 ft, what is the sum of the lengths of the bases?

Back

The sum of the bases (b1 + b2) = 50 * 2 / 5 = 20 ft.

Front

What is the area of a trapezoid with bases of 10 m and 6 m, and a height of 4 m?

Back

A = (10 + 6) * 4 / 2 = 32 m².

Front

If one base of a trapezoid is 12 cm and the other base is 8 cm, what is the area if the height is 3 cm?

Back

A = (12 + 8) * 3 / 2 = 30 cm².

Front

What is the area of a trapezoid with bases of 5 inches and 15 inches, and a height of 2 inches?

Back

A = (5 + 15) * 2 / 2 = 20 in².

Front

How do you find the height of a trapezoid if you know the area and the lengths of the bases?

Back

Height (h) = (Area * 2) / (b1 + b2).

Front

What is the area of a trapezoid with bases of 7 ft and 3 ft, and a height of 4 ft?

Back

A = (7 + 3) * 4 / 2 = 20 ft².
