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 formula for finding the perimeter of a rectangle?

Back

The perimeter of a rectangle is calculated by adding the lengths of all four sides. Formula: Perimeter = 2 × (Length + Width).

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, 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, and then sum them up.

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 formula for the perimeter of a triangle?

Back

The perimeter of a triangle is the sum of the lengths of its three sides. Formula: Perimeter = Side1 + Side2 + Side3.

Front

How do you find the area of a circle?

Back

The area of a circle is calculated using the formula: Area = π × Radius².

Front

What is the relationship between area and perimeter?

Back

Area measures the space inside a shape, while perimeter measures the distance around a shape. They are different properties.

Front

What is the length of a side if the perimeter of a rectangle is 20 cm and the width is 5 cm?

Back

Length = (Perimeter/2) - Width = (20/2) - 5 = 10 - 5 = 5 cm.

Front

If a rectangle has an area of 36 m² and a width of 6 m, what is the length?

Back

Length = Area / Width = 36 m² / 6 m = 6 m.
