Please help! Correct answer only please! I need to finish this assignment by today. The aspect ratio of a rectangular shape is it's length divided by it's width (L/W). If the aspect ratio of a chalkboard is 4:3 and the width is 7 in,

what is the length of the chalkboard?

A. 6.67 in

B. 9.33 in

C. 12 in

D. 14 in

B

Step-by-step explanation:

If the ratio of the length of the chalkboard to the width is 4:3, this means that the length of this one is 7* 4/3=28/3. This can be rewritten as approximately 9.33 inches, or answer choice B. Hope this helps!
