C) To do question "c" you need to assign the different sides of the smaller ractangles, letters. So the length is "X", the height is "Y" and the area is "Z." This is the information we know. X*Y=Z and X/4=Y. Also we can swap around the formula to 4Y=X. To figure out "Z" you need to do 600/6=100 so Z=100. That means that X*Y=100. We know that X=4Y so we cab swap out the "X" for "4Y" so the formula is 4Y*y=100 or 4y^2=100. So 100/4=25 and the square root of 25 is 5. So Y=5 and X=100/5=20. So the perimeter is 20+20+5+5=50.
