Answer

The prison cell had 12.5 more square feet than the shark tank.

Work Step by Step

We know that the area of a rectangle is given by: $Area=length*width$ $A=lw$ We find the areas of the shark cage and prison cell. Prison cell: $Area=5*9=45~feet^2$ Shark cage: $Area=5*(6\frac{1}{2})=5*\frac{13}{2}=\frac{5*13}{2}=\frac{65}{2}=32.5~feet^2$ We subtract the two areas: $45-32.5=12.5=12\frac{1}{2}~feet^2$ Thus the prison cell had 12.5 more square feet than the shark tank.
