PLEASE DON'T GIVE ME UNNECESSARY ANSWER​

Answer 1

Rectangle

Rectangle has 4 sides. The opposite sides are equal in a rectangle. It has 4 edges and 4 vertices. Perimeter of a rectangle defines it's outer surface. And Area defines the inner surface.

Now, Let's move on finding the solution for our question.

We know that,

• $\sf{Length\:=\:40\:{\dfrac{2}{3}}}$
• $\sf{Breadth\:=\:19\:{\dfrac{1}{2}}}$

Area of the Rectangle,

$\boxed{Perimeter\:of\:a\:Rectangle=2\:[Length\:+\:Breadth]}$

Substituting values in Formula, we get,

$\implies\sf{Perimeter\:=\:2\:[40\:{\dfrac{2}{3}}\:+\:19{\dfrac{1}{2}}]}$

$\implies\sf{Perimeter\:=\:2\:[{\dfrac{122}{3}}\:+\:{\dfrac{39}{2}}]}$

$\implies\sf{Perimeter\:=\:2\:[{\dfrac{244\:+\:117}{6}}]}$

$\implies\sf{Perimeter\:=\:2\:[{\dfrac{361}{6}}]}$

$\implies\sf{Perimeter\:=\:{\dfrac{722}{6}}}$

$\implies\sf{Perimeter\:=\:{\cancel{{\dfrac{722}{6}}}}}$

$\implies\sf{Perimeter\:=\:{\dfrac{361}{3}}}$

$\implies\sf{Perimeter\:=\:120{\dfrac{1}{3}}}$

Hence, the perimeter of rectangle ABCB = 120 1/3 cm².
