Area of Trapezoids

Front

What is a trapezoid?

Back

A trapezoid is a four-sided shape (quadrilateral) with at least one pair of parallel sides.

Front

What is the formula for the area of a trapezoid?

Back

The area of a trapezoid can be calculated using the formula: Area = (1/2) * (Base1 + Base2) * Height.

Front

What are the bases of a trapezoid?

Back

The bases of a trapezoid are the two parallel sides.

Front

What is the height of a trapezoid?

Back

The height of a trapezoid is the perpendicular distance between the two bases.

Front

If the bases of a trapezoid are 10 cm and 6 cm, and the height is 4 cm, what is the area?

Back

Area = (1/2) * (10 cm + 6 cm) * 4 cm = 32 cm².

Front

What is the difference between a trapezoid and a rectangle?

Back

A trapezoid has at least one pair of parallel sides, while a rectangle has two pairs of parallel sides and all angles are right angles.

Front

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

Back

Rearrange the area formula: Height = (Area * 2) / (Base1 + Base2).

Front

What is the area of a trapezoid with bases of 8 m and 12 m, and a height of 5 m?

Back

Area = (1/2) * (8 m + 12 m) * 5 m = 50 m².

Front

Can a trapezoid have equal non-parallel sides?

Back

Yes, a trapezoid can have equal non-parallel sides, which is called an isosceles trapezoid.

Front

What is an isosceles trapezoid?

Back

An isosceles trapezoid is a trapezoid where the non-parallel sides are equal in length.
