Answer:
width = 8, length = 42
Step-by-step explanation:
Let x = width, then length = 4x+10.
A = l x w
336 = x(4x+10) put into standard form
4x2 + 10x - 336 = 0 divide by 2
2x2 + 5x - 168 = 0 and solve using the quadratic formula and get
-21/2 and 8, the neg answer will not work, so the width = 8, length = 42
