Front

What is the formula for the area of a trapezoid?

Back

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

Front

What is the formula for the area of a circle?

Back

Area = π * r², where r is the radius.

Front

How do you calculate the area of a composite figure?

Back

Add the areas of the individual shapes that make up the composite figure.

Front

What is the relationship between the circumference of a circle and its area?

Back

The circumference is related to the radius and can be used to find the area using the formula Area = (Circumference²) / (4π).

Front

What is the definition of a trapezoid?

Back

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

Front

What is the difference between perimeter and area?

Back

Perimeter is the total distance around a shape, while area is the amount of space inside the shape.
