Assuming these measurements are in pairs
10m x 10m is 100m2
6m x 4m is 24m2
7m x 3m is 21m2
Total 145m2
65
-15m but -15 metres doesnt exist
6m + 7 - 2m + 1 = 4m + 8 If you meant: (6m + 7) - (2m + 1) = 4m + 6
6m
Area = Length * Width 24 = 6 * Width so width = 4m
18m
use the net to find the lateral area of the prism 3m 6m 3m 6m 15m
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.
-15m but -15 metres doesnt exist
2 - 3m + 7 = 4m - 9 - m - 28 46 = 6m 46/6 = 23/3 = 7.6666 = m
74
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.
It is: 6m
4m - 8 = 6m =>4m - 6m = 8 => -2m = 8 => m = -(8/2) => m = -4
6 * 4 = 24 square metres
6m + 5n - 4m + 7n = 2m + 12n
