Solution:

The width is greater than its length by 8 so

x+8 is the Width

And The Length is

x

if finding the area you will need this:

x(x+8)

and the answer is:

x²+8

Area of steel before cutting:

= (11 + 2x) × (6 + 2x) cm^2

= 66 + 22x + 12x + 4x^2

Quadratic Equation = 4x^2 + 34x + 66

Area of steel after cutting out the 11 × 6 middle:

= 4x^2 + 34x + 66 - 66

Quadratic Equation = 4x^2 + 34x

Add them up and the height h at any time t is:

h = 3 + 14t - 5t^2

Quadratic Equation : -5t^2 + 14t + 3 = 0
