Step by Step Calculation

Back to Top
Step 1 :  

Formulas:


 


Area of rectangle = a * b


 


Perimeter of a rectangle = 2a + 2b


 


Polygon diagonals of rectangle = $\sqrt{a^{2}+b^{2}}$


 


Where,


 


'a' and 'b' = side length


A = Area of rectangle


P = Perimeter of rectangle


p = q = Polygon diagonals of rectangle



Step 2 :  

Put the values in the formula and calculate it further.

  1. The side length of the rectangle is 4 cm and 6 cm. Find area, perimeter and polygon diagonals of a rectangle.


    Step 1 :  

    Given:


     


    a = 4 cm


    b = 6 cm


     


    Formulas:


     


    Area of rectangle = a * b


     


    Perimeter of a rectangle = 2a + 2b


     


    Polygon diagonals of rectangle = $\sqrt{a^{2}+b^{2}}$



    Step 2 :  

    Put the values in the formula and calculate it further.


     


    Area of rectangle = 4 * 6


                             = 24 cm2


     


    Perimeter of rectangle = 2 * 4 + 2 * 6


                                    = 8 + 12


                                    = 20 cm


     


    Polgon diagonals of a rectangle = $\sqrt{4^{2}+6^{2}}$


                                                 = 7.211 cm



    Answer  :  

    Area of rectangle = 24 cm2

     

    Perimeter of rectangle = 20 cm

     

    Polygon diagonals of a rectangle = 7.211 cm



  2. The side length of the rectangle is 11 m and 14 m. Find area, perimeter and polygon diagonals of a rectangle.


    Step 1 :  

    Given:


     


    a = 11 m


    b = 14 m


     


    Formulas:


     


    Area of rectangle = a * b


     


    Perimeter of a rectangle = 2a + 2b


     


    Polygon diagonals of rectangle = $\sqrt{a^{2}+b^{2}}$



    Step 2 :  

    Put the values in the formula and calculate it further.


     


    Area of rectangle = 11 * 14


                             = 154 m2


     


    Perimeter of rectangle = 2 * 11 + 2 * 14


                                    = 22 + 28


                                    = 50 m


     


    Polgon diagonals of a rectangle = $\sqrt{11^{2}+14^{2}}$


                                                 = 17.80 m



    Answer  :  

    Area of rectangle = 154 cm2

     

    Perimeter of rectangle = 50 m

     

    Polygon diagonals of a rectangle = 17.80 m
