For this case, the first thing we are going to do is model the desk as a rectangle.
The area of the rectangle is given by:
A = w * l
Where,
w: width
l: length
Clearing we have:
l = A / w
Substituting values:
l = (15/16) / (5/4)
Rewriting we have:
l = (15/16) * (4/5)
Simplifying we have:
l = (3/4) m
Answer:
The length of the desk in meters is:
l = (3/4) m
