# Parallelogram Formula

A geometric shape with two similar opposite sides and equal opposite angles is a parallelogram. This is termed a parallelogram when the image is two dimensional and if the image is three dimensional, then it is termed as parallelepiped. Given is the shape of a parallelogram:

The equation for area of a parallelogram is,

$\large Area=b\times h$

The equation for perimeter of a parallelogram is,

$\large Perimeter=2\left(b+h\right)$

Where b is the base and h is the height of a parallelogram

### Solved Examples

Question 1: Calculate the area and perimeter of a parallelogram whose base length and height is 4 cm and 11 cm respectively?

Solution:

The given parameters are,
Base length, b = 5 cm;
Height, h = 10 cm

The equation for area of a parallelogram is,

Area = b $\times$ h
Area = 4 $\times$ 11 = 44 cm2

Perimeter of a parallelogram is given by,
Perimeter = 2(b+h)
Perimeter = 2(4+11) = 30 cm
