3rd 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

How do you find the area of a composite shape?

Back

To find the area of a composite shape, divide it into simpler shapes (like rectangles and triangles), calculate the area of each shape, and then add them together.

Front

What is the unit of area?

Back

The unit of area is typically square units, such as square centimeters (cm²), square meters (m²), or square inches (in²).

Front

What is the area of a square with a side length of 5 cm?

Back

Area = Side × Side = 5 cm × 5 cm = 25 cm².

Front

If a rectangle has a length of 8 cm and a width of 3 cm, what is its area?

Back

Area = Length × Width = 8 cm × 3 cm = 24 cm².

Front

What is an irregular shape?

Back

An irregular shape is a shape that does not have equal sides or angles, making it difficult to calculate the area using standard formulas.

Front

How can you estimate the area of an irregular shape?

Back

You can estimate the area of an irregular shape by counting the number of square units it covers on a grid or by breaking it into regular shapes.

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

If a triangle has a base of 6 cm and a height of 4 cm, what is its area?

Back

Area = 1/2 × Base × Height = 1/2 × 6 cm × 4 cm = 12 cm².

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.
