Step-by-step explanation:

Answer 2

Answer:

Area of rectangle is greater by $116^{2}$.

Step-by-step explanation:

Let a be the side of a square, l be the length and b be the breadth of rectangle.

As length of wire is constant, perimeter of both shapes would be same,

⇒4a=2(l+b)

⇒40=2(12+b)

⇒b=18 cm

Area of square=$a^{2}$ =$10^{2}$=$100^{2}$

 

Area of rectangle=lb=12×18=$216^{2}$

⇒ Area of rectangle is greater by $116^{2}$.
