Review Area of Composite figures

Front

What is a composite figure?

Back

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

Front

How do you find the area of a composite figure?

Back

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

Front

What is the formula for the area of a rectangle?

Back

The area of a rectangle is calculated using the formula: Area = length × width.

Front

What is the formula for the area of a triangle?

Back

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

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 yd and a width of 4 yd, what is its area?

Back

Area = 5 yd × 4 yd = 20 yd².

Front

If a triangle has a base of 6 m and a height of 3 m, what is its area?

Back

Area = (6 m × 3 m) / 2 = 9 m².

Front

If a circle has a radius of 3 ft, what is its area?

Back

Area = π × (3 ft)² ≈ 28.27 ft².

Front

What is the total area of a composite figure made of a rectangle (5 yd by 4 yd) and a triangle (base 4 yd, height 3 yd)?

Back

Area of rectangle = 20 yd²; Area of triangle = 6 yd²; Total area = 20 yd² + 6 yd² = 26 yd².

Front

What is the area of a shape if the total area of a composite figure is 384 yd² and the area of one part is 112 yd²?

Back

Area of the other part = 384 yd² - 112 yd² = 272 yd².
