Question

Find the polynomial which represents the perimeter of the rectangle whose length is $2$ more than its breadth.

Answer 1

Let the breadth of the rectangle is $x$

and length of rectangle is $x+2$

Perimeter of rectangle $=$ $2(l+b)$

$=$ $2(x+2+x)$

$=$ $2(2x+2)$

$=$ $4x+4$

So, a required polynomial is $4x+4$
