Multiply your length value by 2.54. One inch is equal to roughly 2.54 centimeters,
Its 20.32 cm btw.
Answer:
We first must solve for x
![9x-x+5x=260\\13x=260\\x=30](https://tex.z-dn.net/?f=9x-x%2B5x%3D260%5C%5C13x%3D260%5C%5Cx%3D30)
When we have x, we put it in to the second equation
![Bx=200\\\\B=\frac{200}{x} \\\\B=\frac{200}{30}\\\\B=\frac{20}{3}](https://tex.z-dn.net/?f=Bx%3D200%5C%5C%5C%5CB%3D%5Cfrac%7B200%7D%7Bx%7D%20%5C%5C%5C%5CB%3D%5Cfrac%7B200%7D%7B30%7D%5C%5C%5C%5CB%3D%5Cfrac%7B20%7D%7B3%7D)
13. 9x^2-36x+36
14. 4x^2+14x+20
Remember area formula for a square is Length times Width.
The area formula for a triangle is 1/2base times height.
