4m

5*4=20 20 square meters.

40 cubic meters

20

5m,4m,3m respectively

It is: 9m +8 -4m +7 -5m = 15

3+4m+5m=214m+5m=21-39m=18m=18/9m=2

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.

30 square meters

Maybe, maybe not. If the smaller of the two dimensions of the room is >= 5m, then yes. Eg if the room is 5m * 6m. But if the room is 3m * 10 m, then not.

4m+9+5m-12=42 9m=45 m=5

4m+9+5m-12=42 9m=45 m=5

3*5 = 15 square meters

you do some fun then do it

8*4*5 = 160 cubic metres.

5m-13n-n+4m= (5+4)m+(-13-1)n= 9m-14n

2n + 4m - 2n + m = 5m

5m x 5m = 25m2 (25 square metres)

48dm is equal to 4m 80cm so 5m 8cm is the longest.

The area of rectangle is : 20.0

YES, because a carpet 5M by 5M is a 25 square metre carpet and would fit into a 30 square metre room.

basically, no. its simple 5m x 5m = 25m2 so a room 30m2 wont work

500cm and 5000mm are equivalent, and also equivalent to 5m. Thus 4m is the shortest length of the three.

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.
