To simplify the fraction, we need to rationalize the denominator by multiplying the numerator and denominator by the conjugate.
The conjugate is the same thing as the denominator with a plus sign instead of a minus sign.
(sqrt(2) + start(5))^2/((sqrt(2) - start(5))(sqrt(2) + start(5)))
FOIL the top and bottom.
The answer is -(7+2sqrt(10))/3
Width=x-6
lenght=x
Perimeter of a parallelogram=2(lenght)+2(width)
Data:
Perimeter=60 m
Therefore:
2(x)+2(x-6)=60
2x+2x-12=60
4x=60+12
4x=72
x=72/4
x=18
Width=x-6=18-6=12
Lenght=x=18
Answer: the lenght would be 18 m, and the width 12 m
