Area = 117 m² width = 9 m
Area (A) = length (L) x width (w)
117 = L * 9

13 = L
Answer: length = 9 m
I would set up a proportion:

The proportion basically says, "if there are 5 kids meals for every 4 adult meals, that means 20 kids meals would mean x adult meals." Just cross multiply and then solve for x:

That means there are 20 kids meals sold and 16 adult meals sold, so the result is:
36 meals in total.
