Area of Trapezoids

Front

What is the formula for the area of a trapezoid?

Back

Area = (1/2) * (Base1 + Base2) * Height

Front

What are the bases of a trapezoid?

Back

The two parallel sides of a trapezoid.

Front

What is the height of a trapezoid?

Back

The perpendicular distance between the two bases.

Front

How do you find the area of a triangle?

Back

Area = (1/2) * Base * Height

Front

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

Back

The area of a trapezoid can be calculated using the same principles as a rectangle, but it involves averaging the lengths of the two bases.

Front

If the bases of a trapezoid are 10 cm and 14 cm, and the height is 5 cm, what is the area?

Back

Area = (1/2) * (10 + 14) * 5 = 60 cm²

Front

What is a composite shape?

Back

A shape made up of two or more simple shapes, such as rectangles and triangles.

Front

How do you calculate the total length of the bases of a trapezoid?

Back

Add the lengths of the two bases together.

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

What is the area of a rectangle with a length of 8 cm and a width of 4 cm?

Back

Area = Length * Width = 8 * 4 = 32 cm²
