What is the formula for the area of a trapezoid?

Back

The area of a trapezoid can be calculated using the formula: A = (1/2) * (b1 + b2) * h, where b1 and b2 are the lengths of the two parallel sides and h is the height.

Front

What is the formula for the area of a triangle?

Back

The area of a triangle can be calculated using the formula: A = (1/2) * base * height.

Front

What is a composite figure?

Back

A composite figure is a shape that is made up of two or more simple geometric shapes.

Front

How do you find the area of a composite figure?

Back

To find the area of a composite figure, calculate the area of each simple shape that makes up the figure and then sum those areas.

Front

What are the units for measuring area?

Back

Area is measured in square units, such as square centimeters (cm²), square meters (m²), or square feet (ft²).

Front

What is the significance of knowing the lengths of missing sides in a geometric figure?

Back

Knowing the lengths of missing sides is crucial for calculating the area and other properties of geometric figures.

Front

How do you calculate the area of a rectangle?

Back

The area of a rectangle can be calculated using the formula: A = length * width.

Front

What is the height of a trapezoid?

Back

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

Front

What is the relationship between the base and height of a triangle?

Back

The base and height of a triangle are used together in the area formula, where the height is the perpendicular distance from the base to the opposite vertex.

Front

What is the area of a square?

Back

The area of a square can be calculated using the formula: A = side², where 'side' is the length of one side of the square.
