The answer is: B. 11
Explanation:
1. The area of a rectangle is:
![A=LW](https://tex.z-dn.net/?f=A%3DLW)
Where
is the length and
is the width.
2. The length of the rectangular-shaped deck is 5 meters longer than its width, therefore:
![L=W+5](https://tex.z-dn.net/?f=L%3DW%2B5)
3. You must substitute this into
:
![66=(W+5)W\\W^{2}+5W-66=0](https://tex.z-dn.net/?f=66%3D%28W%2B5%29W%5C%5CW%5E%7B2%7D%2B5W-66%3D0)
4. Now you must solve for the width. You can use the Quadratic formula, which is:
![W=\frac{-b+/-\sqrt{b^{2}-4ac}}{2a}](https://tex.z-dn.net/?f=W%3D%5Cfrac%7B-b%2B%2F-%5Csqrt%7Bb%5E%7B2%7D-4ac%7D%7D%7B2a%7D)
Where:
![a=1\\b=5\\c=-66](https://tex.z-dn.net/?f=a%3D1%5C%5Cb%3D5%5C%5Cc%3D-66)
5. Subsitute values:
![W=\frac{-5+/-\sqrt{5^{2}-4(1)(-66)}}{2(1)}\\W=6](https://tex.z-dn.net/?f=W%3D%5Cfrac%7B-5%2B%2F-%5Csqrt%7B5%5E%7B2%7D-4%281%29%28-66%29%7D%7D%7B2%281%29%7D%5C%5CW%3D6)
6. Then, the lenght is:
![L=6m+5m\\L=11m](https://tex.z-dn.net/?f=L%3D6m%2B5m%5C%5CL%3D11m)
