We’re calculating perimeter, so we add up the length of all 4 sides, or multiply (l + w) x 2. Since the room is square, we only need the one measurement.
11.4 x 4 = 45.6 feet
Answer:
The two numbers are 52 and 12.
Step-by-step explanation:
x+y=64
x=16+3y
Now, substitute the second equation into the first one.
16+3y+y=64
16+4y=64
4y=48
y=12
Substitute 12 into one of the equations in order to find x.
x=16+3(12)
x=16+36
x=52
