A Parallelogram with Four Right Angles


Introduction for A Parallelogram with Four Right Angles:
Shapes is an important part in geometry. Basically, the shapes that are enclosed with its sides are said to be polygons. The polygons are classified based on their sides. Whenever any polygon which contain four sides, then it is said to be a quadrilateral. There are multiple types of quadrilateral. Parallelogram is one of the type of quadrilateral. In this article, we shall discuss about the parallelogram with four right angles. Also we shall solve problems based on Parallelogram with four right angles.

Parallelogram with Four Right Angles:

The parallelogram with four right angles are said to be a Rectangle.


Basically, Rectangle is same as the parallelogram. The opposite sides of the rectangle are equal and parallel. The four angles measures 90° each, which is the right angles.

Area of a Parallelogram with four right angles:

The area of the rectangle can be determined by using the formula,

Area of Rectangle =  l * w

where l is the length of the rectangle and w is the width of the rectangle.


Perimeter of the parallelogram with four right angles:

The perimeter of a rectangle can be determined by using the formula,

Perimeter of rectangle = 2(l + w)

where l is the length of the rectangle and w is the width of the rectangle

Example Problems Regarding Parallelogram with Four Right Angles:
Example 1:

Find the area of the parallelogram with four right angles, whose length is 8cm and width is 5cm.

Solution:

The parallelogram with four right angles is nothing but the rectangle.

Area of rectangle = l * w , 

where l is the length of the rectangle and w is the width of the rectangle.

Area of rectangle = 8 * 5

= 40 cm2

Therefore the area of the parallelogram with four right angles is 40 cm2.

Example 2:

Find the perimeter of the parallelogram with four right angles, whose length is 10cm and width 5cm.

Solution:

The parallelogram with four right angles is nothing but the rectangle.

Perimeter of rectangle = 2 ( l + w)

where l is the length of the rectangle and w is the width of the rectangle.

Perimeter of rectangle = 2 ( 10 + 5 )

= 2 (15)

= 30 cm

Therefore, the perimeter of the parallelogram with four right angles is 30cm.
