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 the outer sides.

How do you find the perimeter of a rectangle?

Back

To find the perimeter of a rectangle, use the formula: P = 2(length + width).

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

Is the highlighted side part of the perimeter? (If the side is not an outer edge)

Back

No, if the side is not an outer edge, it is not part of the perimeter.

Front

What do you need to calculate the perimeter of a composite figure?

Back

You need to know the lengths of all the outer sides of the figure.

Front

What is the formula for the perimeter of a triangle?

Back

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

Front

What should you do if some lengths are not labeled on a composite figure?

Back

If some lengths are not labeled, you cannot accurately calculate the perimeter until all lengths are known.

Front

If a composite figure has a perimeter of 30 cm, what does that mean?

Back

It means that the total length around the figure is 30 cm.

Front

What is the difference between area and perimeter?

Back

Area measures the space inside a shape, while perimeter measures the distance around a shape.
