What's the length of each way

Question

An architect is designing a rectangular greenhouse. Along one wall is a 7-ft storage area and 5 sections for different kinds of plants. On the opposite wall is a 4-ft storage area and 6 sections for plants. All of the sections for the plants are of equal length. What is the length of each wall?

Answer 1

if x = length of section, then

 

7 ft + 5x = 4 ft + 6x

 

3 = x

 

Therefore the wall is 22 feet long.

 

It is impossible to determine the length of the other two walls.
