19-1=18, and 18/2=9
Do the same to others to check
Answer: x= 8
Step-by-step explanation:
According to the converse of basic proportionality theorem,
If in ΔABC , DE is a line drawn from AB to AC such that 
then, DE is parallel to the third side BC.
Applying converse of basic proportionality theorem, to get NO parallel to KJ, we must have

Hence, the value of x should be 8, so that Line segment N O is parallel to line segment K J.
1. Let's call the short side
and the long side
.
2. The problem says that the short side is 1/3 the length of the long side. So, you can write the following expression:

3. The formula for calculate the area of a rectangle is:

4. Then, you must substitute
and the value of the area into the formula and solve for
(The long side):

5. Now, you can calculate
(The short side):

Therefore, the answer is: 600 feet by 200 feet.
