We obtained the area of the rectangle by multiplying one of its sides by the other. According to the condition of the problem, it was 45 cm ^ 2. Now, in order to find out what the length of one of its sides is equal to, we need to divide this area by the length of the side that we know. We find out what the second side is equal to if the length of the first is 4 cm.

45/4 = 11.25 cm.

Answer: The second side is 11.25 cm long.
