Answer:
since the room is rectangular and has 4 sides
2 sides have the same length
18*2= 36m
80*2=160m
then add the sums...
the answer is 196 meters

Answer:
x is a variable its value can be changed
After simplifying The answer is -8/3
Solving this problem will require a system of equations. Since it's already assigned variables, we can make the equations. They are as follows.
x + y = 13 (The sum of the two numbers, x and y, is 13.)
2x - 3y = 1 (Two times the first number minus three times the second number is 1.)
To solve this system using the substitution method, isolate either x or y in the first equation. I'll isolate y.
x + y = 13
y = 13 - x
Substitute 13 - x for y into the second equation and solve algebraically for x.
2x - 3y = 1
2x - 3(13 - x) = 1
2x - 39 + 3x = 1
5x - 39 = 1
5x = 40
x = 8
Substitute 8 for x into either of the original equations and solve algebraically for y.
x + y = 13
8 + y = 13
y = 5
Check all work by plugging the x- and y-values accordingly into each equation.
x + y = 13 => 8 + 5 = 13
2x - 3y = 1 => 2(8) - 3(5) = 1 => 16 - 15 = 1
