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 are the bases of a trapezoid?

Back

The bases of a trapezoid are the two parallel sides.

Front

How do you find the height of a trapezoid?

Back

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

Front

What is the formula for the area of a trapezoid?

Back

The area (A) of a trapezoid can be calculated using the formula: A = (1/2) * (base1 + base2) * height.

Front

If the bases of a trapezoid are 5 cm and 7 cm, and the height is 4 cm, what is the area?

Back

Area = (1/2) * (5 + 7) * 4 = 24 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 of a trapezoid is 10 m and the other is 14 m, what is the total length of the bases?

Back

Total length of the bases = 10 m + 14 m = 24 m.

Front

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

Back

The height is crucial because it determines how far apart the bases are, affecting the overall area.

Front

How does changing the height of a trapezoid affect its area?

Back

Increasing the height increases the area, while decreasing the height decreases the area.

Front

What is the relationship between the bases and the area of a trapezoid?

Back

The area increases as the lengths of the bases increase.
