## How do you find the perimeter of a region?

To find the perimeter, add together the lengths of the sides. Start at the top and work clockwise around the shape. Area of Polygon = (Area of A) + (Area of B) To find the area, divide the polygon into two separate, simpler regions.

How is perimeter calculated?

To find the perimeter of a rectangle, add the lengths of the rectangle’s four sides. If you have only the width and the height, then you can easily find all four sides (two sides are each equal to the height and the other two sides are equal to the width). Multiply both the height and width by two and add the results.

### How do you find perimeter formula?

The formula for the perimeter of a rectangle is often written as P = 2l + 2w, where l is the length of the rectangle and w is the width of the rectangle.

How to find perimeter of trapezoid in terms of area?

The perimeter of the trapezoid in terms of area is given as P = (sum of the lengths of non-parallel sides) + 2A h A h where A is the area of trapezoid and h is its height. How to Find the Perimeter of Trapezoid? The perimeter of the trapezoid can be found by using the following steps: Step 1: Write the dimensions of all the sides of the trapezoid.

## How do you find the missing side length of the trapezoid?

We can determine the missing side length of the perimeter of the trapezoid by using the following steps: Step 1: Write the given dimensions of the trapezoid. Step 2: Assume the missing side length of the trapezoid to be “x” units. Step 3: Add the lengths of all the sides of the trapezoid and equate the value to the perimeter of the trapezoid.

How do you make a trapezoid into a rectangle?

If you cannot form two right triangles because one side of the trapezoid is perpendicular to the base, just note that this side will have the same measurement as the height, and divide the trapezoid into one rectangle and one right triangle. Label each height line. Since these are opposite sides of a rectangle, they will be the same length.

### How do you label a trapezoid base?

Label the length of the middle section of the bottom base. (This is the bottom side of the rectangle.) This length will be equal to the length of the top base, because opposite sides of a rectangle are of equal length. For example, if the top base of the trapezoid is 6 cm, then the middle section of the bottom base is also 6 cm.
