Mastering The Basics Of Rectangles In Mathematics: Area, Perimeter, And Real-World Applications

Rectangle

a parallelogram with 4 right angles and opposite equal sides

A rectangle is a geometric figure with four straight sides and four right angles, where the opposite sides are equal in length. It is also known as a quadrilateral or a four-sided polygon. The opposite sides of a rectangle are parallel to each other, and the length of the diagonal is equal to the square root of the sum of the squares of the length and width.

The area of a rectangle can be found by multiplying its length by its width. The formula for finding the area of a rectangle is A = l x w where A represents the area of the rectangle, l represents the length, and w represents the width.

The perimeter of a rectangle is simply the sum of all its sides. The formula for finding the perimeter of a rectangle is P = 2(l + w) where P represents the perimeter of the rectangle, l represents the length, and w represents the width.

Rectangles are widely used in the real world, from building and construction to graphic design and computer graphics. They are also used in mathematics as a building block for other geometric shapes, such as squares, trapezoids, and parallelograms.
