Answer 1

Hope it helps....you with your question...

Answer 2

★ AREAS OF 2D FIGURES ★

Area of a Square = Side × Side ( a × a = a² ) 

So, If the side is doubled, then :

⇒ New Side = 2a
∴ New Area = 2a × 2a
                    = 4a²

Thus, Doubling the side length multiplies the area by 4 times.
