Hi!
<h3>Let's set up a proportion and cross multiply to solve. </h3>
<h3>Solve for w</h3>
2 * 12 = 24
24/3 = 8
<u>
</u>
<h3>To find the perimeter of the floor, use this equation</h3>
<em>(l = length</em>
<em>w = width </em>
<em>p = perimeter)</em>
l + l + w + w = p
<u>12 + 12 + 8 + 8 = 40</u>
<h2>The perimeter of the floor is 40 meters. </h2>
Hope this helps! :)

Answer:
A = 3x³ - 22x² + 30x - 36
Step-by-step explanation:
Area of a Rectangle: A = lw
Step 1: Define
l = 3x² - 4x + 6
w = x - 6
Step 2: Substitute and Evaluate
A = (3x² - 4x + 6)(x - 6)
A = 3x³ - 4x² + 6x - 18x² + 24x - 36
A = 3x³ - 22x² + 30x - 36
Answer:
20/3
Step-by-step explanation:
Every nth term takes the form of a + n*d, where a is the first term.
So 7th term = (54 = a + 7d), 13th term = (94 = a + 13d).
equate them both:
94 - 13d = 54 - 7d
40 = 6d
d = 40/6
