what is the expression?

anonymous · Answer

and each tile has an area of what?

anonymous · Answer

$$117r^{4} \over \sqrt{9}r ^{13} $$

anonymous · Answer

Total Area=Area of one tile * number of tiles

anonymous · Answer

Total Area=Area of one tile * number of tiles
=> 117r^4=sqrt(9r^13) *x
=> x=117r^4/sqrt(9r^13)=39/r^(5/2)
