The formula to find the area of a rectangle is
Area=length*width
( area equals length times width)
So you substitute the values in the problem into the equation above.
5 5/8=1 1/2* w
Then you can solve the equation by dividing the 5 5/8 by the 1 1/2, cancelling out 1 1/2 and leaving the w by itself on one half of the equal sign
You are left with
3 3/4 = w
The width of the patio in yards is 3 3/4.
