Question

a rectangular garden has one side length of a and another length of a + 2. find the perimeter of the garden?​

Answer 1

$\Large{\underbrace{\underline{\sf{Understanding\;the\; Question}}}$

Here in this question we have given the length and breadth of rectangle to be a+2 and a respectively and we have to find the perimeter of rectangle, which could be easily find by applying formula of perimeter of rectangle.

$\rule{250}{2}$

Before finding perimeter let us understand what perimeter actually is.

Perimeter→ The length of boundary of a given figure is called it's perimeter.

$\rule{250}{2}$

Now let's find perimeter!

$\underline{\boxed{\sf{Perimeter \;of \:rectangle=2(L+B)}}}\star$

$\sf{Perimeter\:of\: rectangle=2[(a+2)+a]$

$\sf{Perimeter\:of\: rectangle=2[2a+2]$

$\sf{Perimeter\:of\: rectangle=4a+2$

∴ The required perimeter of rectangle is 4a+2.

$\rule{250}{2}$
