We want to list the steps involved in multiplying fractions;
Taking an example;

First steps are;
- Multiply the numerators together
- Multiply the Denominators together

Next is to;
Check to see if the product can be simplified;

So, we get the product to be;
The width of the sidewalk would be 10ft.
Sorry if incorrect
The distance is 19 yards or 18.9 yards:
because tan(10)=opposite/adjacent=3.33/x and x is distance
x=3.33/tan(10)=18.9 yd
C= 3b + 2d
Subtract 3b first.
C-3b = 2d
Divide by 2.
C-3b/2 = d
OR
C-3b
-------- = d Your final answer!
