Answer:
Longest side is 18 m
Step-by-step explanation:
1st side : x -9
3rd : 3(x-9)
If perimeter is 39, then, x + (x-9) + 3(x-9) = 39
5x -36 = 39
5x = 75
x = 15
Therefore,
1st side = 6
2nd side = 15
3rd side = 18
Okay just find something the bottom and the top number can be divided by. Like the first one 9/18. They are bithe dividable by 9 so 9÷9=1. 18÷9=2. Now put one back over two. 1/2. So your answer is one half. This is to help you learn how to do it I hope it helps.

Step-by-step explanation:
euhm ... did u just asked if a figure with h=9inches and b=12inches is rectangular???
Does it matter what the diagonals are etc?
if the frame has angles of 90° and it has two different lengths then it has to be rectangular. The sides of a square would have the same lengths.
