Perimeter of a mirror is 260. The length is x cm. Find the height of the mirror in terms of x

Elenna [48]

$\bf \textit{perimeter of a rectangle}\\\\ P=2(L+h)~~ \begin{cases} L=length\\ h=height\\[-0.5em] \hrulefill\\ P=260\\ L=x \end{cases}\implies 260=2(x+h) \\\\\\ \cfrac{260}{2}=x+h\implies 130=x+h\implies 130-x=h$

Answer:

$\huge\boxed{\sf x = 10}$

Step-by-step explanation:

Hypotenuse = x

Base = 4

Perpendicular = $\sqrt{84}$

<u>Using Pythagoras Theorem:</u>

$\sf H^2 = P^2 + B^2\\\\ x^2 = (\sqrt{84} )^2 + (4)^2\\\\x^2 = 84 + 16\\\\x^2 = 100\\\\Taking \ sq \ root \ on \ both \ sides\\\\x = 10\\\\\rule[225]{225}{2}$

Hope this helped!
