Perimeter of Composite Figures

Front

What is the perimeter of a composite figure?

Back

The perimeter of a composite figure is the total distance around the figure, calculated by adding the lengths of all its exterior sides.

Front

How do you find the perimeter of a composite figure?

Back

To find the perimeter, measure each exterior side and sum all the lengths.

Front

What units are used to measure perimeter?

Back

Perimeter is measured in linear units such as meters (m), centimeters (cm), inches (in), or miles.

Front

What is a composite figure?

Back

A composite figure is a shape that is made up of two or more simple geometric shapes.

Front

If a composite figure has missing side lengths, how can you find the perimeter?

Back

You can find the perimeter by calculating the lengths of the missing sides using given dimensions or properties of the shapes.

Front

Is the highlighted side part of the perimeter?

Back

Yes, any exterior side of a composite figure is part of the perimeter.

Front

What is the formula for the perimeter of a rectangle?

Back

The perimeter (P) of a rectangle is calculated using the formula P = 2(length + width).

Front

What is the formula for the perimeter of a triangle?

Back

The perimeter (P) of a triangle is calculated using the formula P = side1 + side2 + side3.

Front

How do you handle overlapping sides in composite figures?

Back

When calculating the perimeter, do not count overlapping sides more than once.

Front

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

Back

The perimeter is P = 4 * side = 4 * 5 cm = 20 cm.
