Let x = width length = 5x -10 (10 ft less than 5 times width) A = l * w A = (5x-10)*x 2640 = 5x2 -10x 5x2 -10x -2640=0 divide by 5 x2 -2x - 528 = 0 (x-24)(x+22)=0 x-24=0 x=24 width (the other factor would give us a negative length) length = 5*24 -10 length = 110
16. C. 0 means it is at sea level. The question is asking about the elevation of each of the places. 1.3 means the elevation is 1.3 km. If I am wrong than the only other possibility is A.

Hoped I helped!
