Let length be l and breadth be b.
l = 4b. (I)
Perimeter: 12.5 km
Perimeter, P = 2(l+b)
P = 2( 4b +b) = 12.5
4b + b = 12.5/2
5b = 6.25
Therefore, b = 6.25/5
= 1.25 km
Now, from 1,
l = 4*1.25
= 5 km
Area = l*b
= 5*1.25
= 6.25 km^2
25.8>2.5x+5, so 20.8=2.5x, so 8.32=x. Therefore, 8 containers will be completely full.

Step-by-step explanation:
Answer:
m = 7
Step-by-step explanation:
2m + -4 = 10
Reorder the terms:
-4 + 2m = 10
Solving
-4 + 2m = 10
Solving for variable 'm'.
Move all terms containing m to the left, all other terms to the right.
Add '4' to each side of the equation.
-4 + 4 + 2m = 10 + 4
Combine like terms: -4 + 4 = 0
0 + 2m = 10 + 4
2m = 10 + 4
Combine like terms: 10 + 4 = 14
2m = 14
Divide each side by '2'.
m = 7
Simplifying
m = 7
