7/10 is 0.7
0.7 x 16 yields 11.2
11.2 is also 11 1/5
or 56/5
I believe the answer is 8

Check the picture below, you can pretty much count the units off the grid for the length and width.
recall area = length * width.
You will have to divide 140 by 8 and it will give u P you already know R equals 8
