Question

What is the perimeter of rectangle​

Answer 1

The perimeter is the length of the outline of a shape. To find the perimeter of a rectangle or square you have to add the lengths of all the four sides. x is in this case the length of the rectangle while y is the width of the rectangle. The area is measurement of the surface of a shape.

Formula = 2×(l+b)

What is Perimeter?

The distance around a two-dimensional shape is called Perimeter. Example: the perimeter of this rectangle is 3+7+3+7 = 20. The perimeter of a circle is called the circumference.

Why the perimeter of circle is called circumference ?

If the boundary consists of straight sides , the total length of the boundary is called perimeter. If the boundary consists of curved lines or arc , the total length of the boundary is called Circumference.

Some Formulas:

Geometric Shape ⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀Perimeter Formula

Parallelogram.= ⠀⠀⠀ ⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀ 2(Base + Height)

Triangle = ⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀a + b + c

Rectangle =⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀2(Length + Width)

Square = ⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀ 4a [a =Length of a side]

Trapezoid= ⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀ a + b + c + d [a, b, c, d being the sides of the trapezoid]

Kite= ⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀ 2a + 2b [a = Length of the first pair b = Length of the second pair]

Rhombus = ⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀ 4 x a [a = Length of a side]

Hexagon.= ⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀ 6 x a
