Answer:

Step-by-step explanation:
Rewrite the system of equations as:

Subtract the second equation from the first to isolate
:

Plug in
into any of the equations above and solve for
:

Verify that the solution pair
works 
Therefore, the solution to this system of equations is:

H=45d h stands for hours and 45d means 45 minutes per day
Area = Length x width
Area = 12 x 8.6
Area = 103.2 square yards.
