Area of Composite Shapes

Front

What is the area of a rectangle?

Back

The area of a rectangle is calculated by multiplying its length by its width. Formula: 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 a composite shape?

Back

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

Front

How do you find the area of a composite shape?

Back

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

Front

What is the area of a square?

Back

The area of a square is calculated by squaring the length of one of its sides. Formula: Area = Side × Side.

Front

What is the formula for 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 10 cm and a width of 5 cm, what is its area?

Back

Area = Length × Width = 10 cm × 5 cm = 50 cm².

Front

If a triangle has a base of 8 cm and a height of 5 cm, what is its area?

Back

Area = 1/2 × Base × Height = 1/2 × 8 cm × 5 cm = 20 cm².

Front

What is the area of a composite shape made of a rectangle (4 cm by 6 cm) and a triangle (base 4 cm, height 3 cm)?

Back

Area of rectangle = 4 cm × 6 cm = 24 cm²; Area of triangle = 1/2 × 4 cm × 3 cm = 6 cm²; Total area = 24 cm² + 6 cm² = 30 cm².

Front

What is the area of a circle with a radius of 3 cm?

Back

Area = π × Radius² = π × (3 cm)² ≈ 28.27 cm².
