4m+9+5m-12=42 9m=45 m=5
4m + 9 + 5m - 5 = 42 9m + 4 = 42 9m = 38 m = 38/9
M = 5 * * * * * 4m + m - 11 = 9 or 5m - 11 = 9 so that 5m = 20 and then m = 4, NOT 5.
The perimeter of 4 meters by 5 meters is 18. Is the figure a square? if it is then the answer is 18m squared. The first answer is correct if the shape is a parallelogram; the second is rubbish. A square cannot be 4m by 5 m because one of the defining characteristics of a square is that its sides are the same length! The perimeter is the length (therefore metres, NOT m sq) around the shape. 4m+5m+4m+5m = 18m.
4m + 9 + 5m - 12 = 42 9m -3 = 42 9m = 42 + 3 9m = 45 m = 5
18m
3+4m+5m=214m+5m=21-39m=18m=18/9m=2
4m+9+5m-12=42 9m=45 m=5
5m,4m,3m respectively
Rectangles are really simple. The perimeter is twice the length plus twice the width (in this case 4m x 2 = 8m, 5m x 2 = 10m, and 8m + 10m = 18m). The area is simply the length times the width (in this case, 4m x 5m = 20m2).
4m + 9 + 5m - 5 = 42 9m + 4 = 42 9m = 38 m = 38/9
M = 5 * * * * * 4m + m - 11 = 9 or 5m - 11 = 9 so that 5m = 20 and then m = 4, NOT 5.

simplified it equals, 9m+8
5*4=20 20 square meters.
4m + 9 + 5m - 12 = 42 9m -3 = 42 9m = 42 + 3 9m = 45 m = 5
It is: 9m +8 -4m +7 -5m = 15
