Answer:
16.7 cm
Step-by-step explanation:
Area of a triangle = ½*base*height
Area of the shaded region = area of triangle = 100.2 cm³
base = w
height = 12 cm
Plug in the value into the equation:
½*w*12 = 100.2
6w = 100.2
w = 100.2/6
w = 16.7 cm

We have
The minimum number is obtained when more cent stamps are used
Here cannot be greater than 
since 
Substitute 
Not possible since is not a fraction
Substitute 
Not possible since is not a fraction
Substitute 
Possible
Hence minimum number of stamps is
No you had it right, it is around the 18 / 3 and the 5 + 1
