Let the width be "x" cm.
Then the length is "x+12" cm
And the area = x(x+12) = x^2+12x cm^2
----------------------------
Change the dimensions:
width = "x-2" cm
length = "x+10" cm
New area = (x-2)(x+10) = x^2 + 8x - 20 cm^2
------------------
Equations :
Old area - New area = 108 cm^2
x^2+12x -(x^2 + 8x - 20) = 108
4x + 20 = 108
4x = 88
x = 22 cm (original width)
x+12 = 24 cm (original length)

Answer:
2 hours 15 minutes
Step-by-step explanation: 45 - 30 is 15 so now you just have to subtract the hours and since 11:00 only goes to 12 you would go to one after that so 1:00 is like 13 so 11 - 13= 2 so your answer is 1 hours and 15 minutes
I wrote my decision of this example on a piece of paper.
