K • 60 = 54
54 : 60 = 0.9
0.9 • 60 = 54
So the value of k is 0.9
2.5-2.1=0.4
41+51=92
0.4x2+92x2=184.8 units
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! :)

The answer would be B because difference means subtracting so the answer would be x-6
4^2 + 7^2 = c^2
This is because we know that the hypotenuse (c) is always diagonal to the right triangle, so the legs are 4 and 2 (a and b). There is your equation!
Good luck!
