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

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

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 squares), calculate the area of each shape, and then add them together.

Front

What is the formula for 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 shape that is made up of two or more simple shapes, such as rectangles, squares, and triangles.

Front

If a rectangle has a length of 6 cm and a width of 4 cm, what is its area?

Back

Area = Length × Width = 6 cm × 4 cm = 24 cm².

Front

What is the area of a shape with a length of 9 cm and a width of 5 cm?

Back

Area = Length × Width = 9 cm × 5 cm = 45 cm².

Front

If a square has a side length of 3 cm, what is its area?

Back

Area = Side × Side = 3 cm × 3 cm = 9 cm².

Front

What is the area of a triangle with a base of 10 cm and a height of 5 cm?

Back

Area = 1/2 × Base × Height = 1/2 × 10 cm × 5 cm = 25 cm².

How do you calculate the area of a shaded region in a composite shape?

Back

To calculate the area of a shaded region, find the total area of the composite shape and subtract the area of the unshaded part.
