Ratio of squares is 25/36

Ratio of sides = 5/6

Length could be any multiple of this
5, 10 , 15

could somebody tell me how 8/5 is possible??? could the ratio of the side be 8/5: 8/6 ???

Usually question mention countertop is a square or rectangle , but in this question nothing is mentioned about the countertop .

Does " A countertop of uniform width " means it is a Square countertop ?

Hii

Since, it is given that width is constant, it is a rectangle. It might be a square (a special form of rectangle) but we have to consider a general case.
Always consider more general case unless specified.
I Hope it clears your doubt.
