12m2
The expression (-a 6m - 3a 2m) can be simplified by factoring out the common terms. It can be rewritten as (-a(6m + 3 \cdot 2m)). Simplifying further, it becomes (-a(6m + 6m) = -a(12m)) or (-12am).
Perimeter = 2m Area = 0.25m2
1m and 11m 2m and 10m 3m and 9m 4m and 8m 5m and 7m. The next one, 6m and 6m, would be a square.
6m + 5n - 4m + 7n = 2m + 12n
Only if they are congruent. One of them could be the a rotation of the other - eg 4m x 6m and 6m x 4m.

6m + 7 - 2m + 1 = 4m + 8 If you meant: (6m + 7) - (2m + 1) = 4m + 6
Perimeter = 2m Area = 0.25m2
The surface area depends on the shape, not just the length of sides.
1m and 11m 2m and 10m 3m and 9m 4m and 8m 5m and 7m. The next one, 6m and 6m, would be a square.
Perimeter is 36 mArea is 72 square m
8m + (4n - 6m) + 9n =8m + 4n - 6m + 9n =(8m - 6m) + (4n + 9n) =2m + 13n
The area of rectangle is : 56.0
6m + 5n - 4m + 7n = 2m + 12n
Only if they are congruent. One of them could be the a rotation of the other - eg 4m x 6m and 6m x 4m.
6m x 2m, on average.
