Question

5) The unlike terms in perimeter of___
and___​

Answer 1

The unlike terms in perimeter of $2y$ and $2y²$

Solution: As we know, Sum of all sides of the given figure is called perimeter.

From the figure (i)

Perimeter = Sum of all sides

$=2x+y+2x+y=4x+ {\boxed{2y}}$

$\huge{ \overline{ \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: }}$

From the figure (ii)

Perimeter = Sum of all sides

$=x+y²+x+y²=2x+ {\boxed{2y²}}$

Hence, The unlike terms in perimeter of $2y$ and $2y²$
