What is the Parallelogram’s Area?

A parallelogram’s area is the space bounded by the parallelogram in a provided 2-dimension space. As stated earlier, a parallelogram is a particular kind of quadrilateral having 4 sides, as well as the pair of opposite sides, are parallel. With a parallelogram, the opposite sides are an equal length and the opposite angles are also an equal measure. Because the rectangle and the parallelogram have properties that are similar, the rectangular’ s area equals the parallelogram’s area.

Ways to Calculate a Parallelogram’s Area

Step one: Note down this formula: A = bh. A stands for the area, while b stands for the parallelogram’s length, and h stands for the parallelogram’s height.
Step two: Find the parallelogram’s base. The base equals the length of the bottom side of a parallelogram.
Step three: Find the parallelogram’s height. The height is the length a perpendicular line has to go from the bottom to the top of a parallelogram.
Step four: Multiply the height and the base together.

What is the Square’s Area?

Squares are closed 2-dimensional shapes having 4 equal sides as well as 4 equal angles. The square’s 4 sides create the 4 angles at the vertices. The total of the full length of the sides of a square is the perimeter, as well as the full space the square occupies, is the square’s area. It’s a quadrilateral with these properties.

  • Its opposite sides are parallel.
  • All 4sides are the same.
  • All the angles are 90°.

The formula to determine the area of a square when the sides are provided is:
Area of a square = \ Side \times Side \ = \ s^2

A square’s area may additionally be calculated via the assistance of the square’s diagonal. The formula utilized for finding a square’s area if the diagonal is provided is:
Area of a square using diagonals =  \ \frac{Diagonal^2}{2}

What is the Rectangle’s area?

The area of a rectangle is calculated via the sides. Usually, a rectangle’s area equals the product of its length and width. The rectangle’s perimeter, though, equals the total of all its 4 sides. So, the rectangle’s area is described as the area encompassed by the perimeter. Rectangles are quadrilaterals whose opposite sides are equal and parallel to one another. Because rectangles have 4 sides, there are also 4 angles. All the rectangle’s angles equal 90 degrees; so, all the rectangle’s angles are right angles.

Formula for Determining the Area of a Rectangle

A rectangle’s area is determined in units via multiplying the width (or breadth) by the rectangle’s length.
Area of a Rectangle A \ = \ l \times b

Rectangles

Follow these steps to determine the area:

  • Step one:  Write down the length and width dimensions using provided data
  • Step two: Multiply the values of the length and width 
  • Step three: Write down the solution in square units
