Hmmmm, a few questions.
Is 11 units the entire height or just that of the rectangle?
Do you know what shape the top section is?
Hi,
The top section is not defined so I would assume that the answer would be in terms of an unknown quantity If the top section has a lenght of X and the circular section is a quarter circle an equation can be written.One thing is obvious i.e. the area must be less than 55
