Answer:
Width: 10.5 feet
Length: 31.5 feet
Step-by-step explanation:
Let x represent width of the concrete slab.
We have been given that the length of a concrete slab is three more than three times the width. So length of the slab would be .
We are also told that the area of slab is 330 square feet. We can represent this information in an equation as:
Now, we will take square root of both sides.
Therefore, the width of slab is approximately 10.5 feet.
The length of the slab would be .
Therefore, the length of slab is approximately 31.5 feet.
