What is a composite figure?

Back

A composite figure is a shape that is made up of two or more simple geometric shapes, such as rectangles, triangles, and circles.

How do you find the area of a composite figure?

Back

To find the area of a composite figure, divide it into simpler shapes, calculate the area of each shape, and then sum those areas.

Front

What is the area of a rectangle?

Back

The area of a rectangle is calculated by multiplying its length by its width (Area = length × width).

Front

What is the area of a triangle?

Back

The area of a triangle is calculated using the formula: Area = 1/2 × base × height.

Front

What is the area of a circle?

Back

The area of a circle is calculated using the formula: Area = π × radius².

If a composite figure consists of a rectangle and a triangle, how do you calculate its total area?

Back

Calculate the area of the rectangle and the area of the triangle separately, then add the two areas together.

What is the formula for the area of a trapezoid?

Back

The area of a trapezoid is calculated using the formula: Area = 1/2 × (base1 + base2) × height.

Front

What units are used to measure area?

Back

Area is measured in square units, such as square meters (m²), square centimeters (cm²), or square inches (in²).

Front

How can you estimate the area of irregular shapes?

Back

To estimate the area of irregular shapes, you can use grid paper to count the number of squares that fit inside the shape.
