Well to find this first you will divide the area by the length. If you can use a calculator just put 11.875/4.75 which gives you as your width 2.5. If you can't then change them into irregular fractions so... 11 7/8 --> 95/8 4 3/4 --> 19/4 Then divide them 95/8 / 19/4 95/8 * 4/19 380/152= 2.5 or 2 1/2
