Amir bought a rectangular plot of land.
He knows that the area of the plot is represented by the polynomial expression
x^2-6x+5, and that the longest side measures 199 meters.
What is the perimeter of the plot of land?
:
Find the length of the shorter side
s = %28x%5E2-6x%2B5%29%2F199
:
P = 2L + 2W
:
P = 2%28x%5E2-6x%2B5%29%2F199 + 2(199)
:
P = %282x%5E2-12x%2B10%29%2F199 + 398
:
P = %282x%5E2-12x%2B10%2B199%28398%29%29%2F199
:
P = %282x%5E2-12x%2B10%2B79202%29%2F199
:
P = %282x%5E2-12x%2B79212%29%2F199
