Area of Trapezoids

Front

What is a trapezoid?

Back

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

Front

What are the bases of a trapezoid?

Back

The bases of a trapezoid are the two parallel sides.

Front

How do you calculate 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 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 16 cm, and the height is 5 cm, what is the area?

Back

Area = (1/2) * (10 cm + 16 cm) * 5 cm = 65 cm².

Front

What is the total length of the bases in a trapezoid?

Back

The total length of the bases is the sum of the lengths of the two bases.

Front

If one base is 12 m and the other is 18 m, what is the total length of the bases?

Back

Total length of the bases = 12 m + 18 m = 30 m.

Front

What is the area of a trapezoid with bases of 8 in and 12 in, and a height of 4 in?

Back

Area = (1/2) * (8 in + 12 in) * 4 in = 40 in².

Front

What is the significance of the height in calculating the area of a trapezoid?

Back

The height is crucial as it determines how 'tall' the trapezoid is, affecting the area calculation.

Front

If a trapezoid has an area of 54 cm² and bases of 6 cm and 12 cm, what is the height?

Back

Using the area formula: 54 = (1/2) * (6 + 12) * Height, the height is 6 cm.
