Area of Composite Figures Unit 4

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 triangle?

Back

The area of a triangle is calculated using the formula: Area = (base × height) / 2.

Front

What is a composite figure?

Back

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

Front

How do you calculate the area of a composite figure?

Back

To calculate the area of a composite figure, find the area of each simple shape and then sum them up.

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 5 ft and a width of 3 ft, what is its area?

Back

Area = length × width = 5 ft × 3 ft = 15 ft².

Front

What is the area of a triangle with a base of 4 cm and a height of 3 cm?

Back

Area = (base × height) / 2 = (4 cm × 3 cm) / 2 = 6 cm².

Front

How do you find the area of a circle with a radius of 7 in?

Back

Area = π × radius² = π × (7 in)² ≈ 153.94 in².

Front

What is the area of a composite figure made of a rectangle (length 6 m, width 4 m) and a triangle (base 4 m, height 3 m)?

Back

Area of rectangle = 6 m × 4 m = 24 m²; Area of triangle = (4 m × 3 m) / 2 = 6 m²; Total area = 24 m² + 6 m² = 30 m².

Front

What is the total area of a figure that consists of a square (side 5 in) and a circle (radius 3 in)?

Back

Area of square = side² = (5 in)² = 25 in²; Area of circle = π × (3 in)² ≈ 28.27 in²; Total area = 25 in² + 28.27 in² ≈ 53.27 in².
