Perimeter of a square = 4*l
Now, l= 2m 45 cm = 2*100 + 45 cm = 245cm
P = 4 * 245 = 980 cm^2
Perimeter of a rectangle = 2(l+b)
Now, l = 1m 25cm = 100 + 25 = 125 cm
b = width = 191 cm
P = 2 ( 125 + 191) = 2*316 = 632 cm^2
Since 980 > 632, Perimeter of the given square is greater than the perimeter of the rectangle.
Thankyou!
