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.
3*(2m + 1) is equivalent.
74
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.

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.
2m + 13n
