<h2>
Therefore the length of the living room = 24 ft</h2>
Step-by-step explanation:
Given that , Consuelo's living room is in the shape of rectangle and has an area of 360 square feet and the width of the living room is
its length
Let ,the length of the living room is = x ft
Then width =
ft
Therefore the area of the living room =![x \times \frac {5}{8}x ft^2](https://tex.z-dn.net/?f=x%20%5Ctimes%20%5Cfrac%20%7B5%7D%7B8%7Dx%20ft%5E2)
According to problem,
![x\times \frac {5}{8}x = 360](https://tex.z-dn.net/?f=x%5Ctimes%20%5Cfrac%20%7B5%7D%7B8%7Dx%20%3D%20360)
⇔![\frac{5}{8}x^2=360](https://tex.z-dn.net/?f=%5Cfrac%7B5%7D%7B8%7Dx%5E2%3D360)
⇔![x^2 = \frac{360\times 8}{5}](https://tex.z-dn.net/?f=x%5E2%20%3D%20%5Cfrac%7B360%5Ctimes%208%7D%7B5%7D)
⇔![x^2 = 576](https://tex.z-dn.net/?f=x%5E2%20%3D%20576)
⇔![x=\sqrt{576}](https://tex.z-dn.net/?f=x%3D%5Csqrt%7B576%7D)
⇔![x = 24](https://tex.z-dn.net/?f=x%20%3D%2024)
Therefore the length of the living room = 24 ft

Answer:
Step-by-step explanation:
Answer:
42
Step-by-step explanation:
let the number be x
4/7 of x
(4/7) × x
4x/7
As stated in the question:
x=4x/7+18
=x-4x/7=18
=(7x-4x)/7=18
=3x/7=18
3x= 18×17
3x= 126
x=126/3
x=42
