Answer: 4m²-6m+12 or 2(2m²-3m+6)
Explanation:
To find the perimeter, we use the formula
. 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).
