Answer:
a) Let Kim's age be k, then Kim's sister's age is k/2
k+
=24
b) k+
=24
1
k=24
k=16
=8
Kim's age is 16 while her sister's age is 8.
As there are 81 tiles total, that makes your area 81. Being a square, that makes your area equation A=s^2. As you need a side, this makes your equation s=√A. Plugging in 81 as A, we get s=√81=9, so an edge has 9 tiles.
