Perimeter, Area and Volume formulas

In this page we are going to learn about various Formulas for Perimeter Area and Volume of various geometrical shapes and figures. For your knowledge a perimeter is the path that surrounds or encompasses  a two-dimensional shape.

While Volume is the quantity of a three-dimensional space enclosed  by a closed surface.

And Area is the quantity that expresses the extent of a two-dimensional figure or shape.

Formulas For Perimeter Area Volume

Perimeter, Area and Volume formulas for various shapes:-

  • Geometry is a branch of mathematics that deals with different shapes and sizes. It can be divided into two different types: Plane Geometry and Solid Geometry
  • Plane Geometry deals with shapes such as circles, triangles, rectangles, square.
  • Solid Geometry is concerned in calculating the length, perimeter, area and volume of various geometric figures and shapes. Here are some basic formulas which can be used to calculate the length, area, volume, and perimeter of various shapes and figures.

Formulas For Perimeter Area Volume:-

  • Formulas for Square

    • Perimeter: 4 × a
    • Area: \frac{p\times q}{2}
    • Diagonals
      p = p = \sqrt{4a^{2} – q^{2}}
      q = p = \sqrt{4a^{2} – q^{2}}
Formula for Rhombus
  • Trapezium formulas
    • Perimeter: a + b + c + d
    • Area: \frac{1}{2} × (sum of parallel sides) × distance between them
    • To find thee distance between parallel sides you will have to convert trapezium to rectangle and then use PYTHAGORAS THEOREM.
