Answer:
The length is 72
Step-by-step explanation:
length x width = area
9 x length = 648
length = 72
A= l*w
168= 14*w
Divide both sides by 14
168/14= 14w/14
12=w
Final answer: 12 ft (I'm not sure if you meant to switch the order of b and c).
Add them all together and multiply by 2
1 and 3 are common factor
150 = 2 * 3 * 5 * 5. So the code for the door is 2355 in some order.
