Answer:
The length is 9cm
Explanation:
Formula = A = l * w
We have the width which is 3
And we have the area which is 27
All we need to do is work backward
A = l * w
27 = l * 3
27/3 = l * 3/3
9 = l
The length of the rectangle is 9
We can use that to check our work and see if its correct
Check
A = l * w
A = 9 * 3
A = 27 CORRECT
Now we know it's correct
Hope this helped!
