Verified answer

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(1+b )

40=2(12+b)

b=18 cm

Area of square=a2 = 102 = 100 cm2

Area of triangle= 1b = 12×8 = 216 cm2

⇒ Area of rectangle is greater by 116cm2
