Front

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 by 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.

Front

If a rectangle has a length of 5 cm and a width of 4 cm, what is its area?

Back

Area = 5 cm × 4 cm = 20 cm².

Front

If a triangle has a base of 6 cm and a height of 3 cm, what is its area?

Back

Area = 1/2 × 6 cm × 3 cm = 9 cm².

Front

What is the formula for the area of a composite figure made of a rectangle and a triangle?

Back

Area = Area of rectangle + Area of triangle.

Front

If a composite figure consists of a rectangle (5 cm by 4 cm) and a triangle (base 4 cm, height 3 cm), what is the total area?

Back

Area of rectangle = 20 cm²; Area of triangle = 6 cm²; Total area = 20 cm² + 6 cm² = 26 cm².

What units are used to measure area?

Back

Area is measured in square units, such as cm², m², in², etc.
