Question

L= 20 cm , B = 18 cm. Perimeter =​

Answer 1

• As per the data given in the question, we have to determine the perimeter of a rectangle.

       Given data:- Length=$20cm.$

                             Breadth=$18cm.$

       To find:- the perimeter of rectangle.

       Solution:-

• We know that rectangle has four sides, the opposite sides of the  rectangle are equal to each other.
• The sum of all interior angles is $360 degree.$

• The perimeter of a triangle is

          $=2(length+breadth)\\=2(20+18)\\=2\times38\\=76cm^{2}.$

      Hence, the perimeter of the rectangle is $76cm^{2}.$

Answer 2

Step-by-step explanation:

find the perimeter of the rectangles whose:-l=22cm,b=15cm
