Answer: 4m²-6m+12 or 2(2m²-3m+6)

Step-by-step explanation:

To find the perimeter, we use the formula [tex]P=2l+2w[/tex]. Since we are given the length and width, you plug them in and solve.

2(6-5m+6m²)+2(2m-4m²)              [distribute]

12-10m+12m²+4m-8m²                  [combine like terms]

4m²-6m+12 or 2(2m²-3m+6)

Now, we know that the perimeter is 4m²-6m+12 or 2(2m²-3m+6).
