The perimeter of a rectangle is the sum of all its sides. As a formula, this is
P = w + w + l + l = 2w + 2l = 2(w + l),
where P is perimeter, w is the width, and l is length.
Let's apply this formula to your question and substitute given information, then solve for l.
P = 2(w + l)
10x + 6 = 2(3x - 3 + l).
10x + 6 = 6x - 6 + 2l
4x +12 = 2l
l = 2x + 6
Started at first floor
went up 18 floors, so now we are at 1+18 or 19th floor
then cam down 11 floors, so now we are at 19-11 or 8th floor
then went up 16, so now at 16+8 or 24th floor
it stopped at 24th floor

Answer:
Answer:.1.77
Step-by-step explanation:
