# Parallelograms, Trapeziums, Rhombuses and Kites

## Perimeter of Parallelograms

Finding the perimeter of Parallelograms is easy, all you have to do is **measure the 4 sides of the parallelogram**. (A + A + B + B) or (2A + 2B)

The **top and bottom** sides of the parallelogram should be **equal**, and the** two sides **of the parallelogram should also be **equal**.

**Area of Parallelograms**

Finding the area of parallelograms is easy, all you have to do is **multiply the base by the height**.

## Perimeter of Trapeziums

Finding the perimeter of Trapeziums is pretty easy, all you have to do is **measure the 4 sides of the Trapezium. **(A + B + C + D)

**Area of Trapeziums**

Finding the area of trapeziums is a bit more difficult, but all you have to do is **add the top and bottom numbers together then divide by 2**, and **multiply by the height**.

## Perimeter of Rhombuses

Finding the perimeter of Rhombuses is pretty easy, all you have to do is** measure the 4 sides of the Rhombus**. Since all four sides of a Rhombus are the same, you can just use the formula (**4A**)

**Area of Rhombuses**

Finding the area of Rhombuses is a bit more difficult, but all you have to do find the **values of the diagonals, multiply them together then half the answer**. A rhombus is essentially** half of a rectangle!**

## Perimeter of Kites

Finding the perimeter of Kites is pretty easy, all you have to do is **measure the 4 sides of the Kite**.

**Area of Kites**

Finding the area of kites is the same as the area as finding the area of a Rhombus. Find the **values of the diagonals, multiply them together then half the answer. A kite is essentially half of a rectangle!**
