6*4/2
The area of a decagon with a side of 4m is 123.1m2
To find total area of a room, you multiply the room's dimensions. So if you have a room that is 4 meters by 5 meters, you would multiply the two to find total square meters. Which in this case would be 20 square meters.

6m and one side is 4m what isthe length of the other side
Only if they are congruent. One of them could be the a rotation of the other - eg 4m x 6m and 6m x 4m.
4m - 8 = 6m =>4m - 6m = 8 => -2m = 8 => m = -(8/2) => m = -4
6m + 5n - 4m + 7n = 2m + 12n
6m + 7 - 2m + 1 = 4m + 8 If you meant: (6m + 7) - (2m + 1) = 4m + 6
Assuming these measurements are in pairs 10m x 10m is 100m2 6m x 4m is 24m2 7m x 3m is 21m2 Total 145m2
Area = Length * Width 24 = 6 * Width so width = 4m
To work out the area of a square or a rectangle, all you need to do is multiply the length by the width. In this case the room is the rectangle, and its length is 6 metres and its width is 4 metres. So its area is 6m x 4m = 24sqm.
30m
2m + 13n
The area of 4m by 4m is 16 square meters.
