Answer:
312
Step-by-step explanation:
First we find the measure of the basea and that is 144 becuase 12x12
To find one side we do b*h over 2 and that is 7x12/2 which is 42 then we know that there are 4 more of those sides and we get 42*4 168
When we add 144+168 we will get 312
The answer is 8.333333 it goes on and 3 is repeating.
