Answer: The length should be 9.
Step-by-step explanation:
Step 1. The formula to find area is A (area)= L (length) * W (width)
Step 2. After you substitute the given information it will be 54 = L* 6
Step 3. Now solve this equation 54= 6L
step 4. 54 divided by 6 will give you 9 which is the length. Therefore, the answer is L=9.
