Question

Find the perimeter and Area of a rectangle of

a) L=16.5cm,B=12cm​

Answer 1

Answer:

perimeter=56 area=192

Answer 2

• We have to evaluate the above expression by using the given data.

             Given data:- $L=16.5\ cm,B=12\ cm.$

             To find:- Value of above expression.

             Solution:-

• All side of a rectangle is 90°.
• The perimeter of the  rectangle is

           $P=2(l+w).$

           here B=W

            So that

           $P=2(l+w)\\\Rightarrow p=2(16.5\ cm + 12\ cm)\\\Rightarrow p= 57\ cm.$

    Hence we will get the perimeter of a rectangle is $57\ cm.$

• The Area of a rectangle is

           $A=L\times B.$

        Therefore,

          $A=L\times B\\A=16.5\ cm \times 12\ cm\\A=198\ cm.$

    Hence we will get the area of a rectangle is $198\ cm.$
