# How do you find the perimeter and area of a composite shape?

## How do you find the perimeter and area of a composite shape?

Add up the length of all the sides to get the perimeter. Calculate the area of the composite figure by adding up the areas of the smaller shapes that make up the composite figure . The figure is made up of rectangles. To find the length of side A, look at the two rectangles that make up the figure.

## How do you find the perimeter of a composite shape?

To find the perimeter, we simply add up the lengths of each outside edge. It may be helpful to look out for number bonds when adding the sides. For example, 7 + 3 = 10. The total of all of the outer sides is 36, so the perimeter is 36 cm.

What is the area of composite shapes?

To calculate the area of a composite shape you must divide the shape into rectangles, triangles or other shapes you can find the area of and then add the areas back together. You may have to calculate missing lengths before finding the area of some of the shapes.

What is the formula for composite shapes?

Using the formula for the area of the composite shape, Area of composite shape = Area of rectangle + area of the square. ⇒ Area of composite shape = 14+9 = 23 square inches. Therefore, the area of the given composite shape is 23 square inches.

### How do you calculate the area of composite shapes?

To find the area of composite shapes you just need to break down the shape into individual pieces and calculate their separate pieces then add them back together again to find a total area. Another way of finding the area of composite shapes is to use a subtraction model.

### How do you find the perimeter of a composite figure?

The perimeter of the composite figure is the distance around the figure. It is found by adding each of the side lengths around the figure.

What are different shapes have the same perimeter?

mfb said: There are examples, but they are a bit harder to find. A triangle and a suitable trapezoid are the easiest examples. Thinking about it, two suitable trapezoids are a much easier example of two different shapes with the same area and perimeter. Jun 9, 2020.

How do you calculate the area of a compound shape?

To find the area of a compound shape, follow these simple steps: Step 1: Work out the missing lengths around the edge of the compound shape. Step 2: Divide your L shape into two rectangles. Step 3: Work out the area of each rectangle. Step 4: Add the areas of the rectangles together to give the total area of the L shape.
