Area of parallelogram=base×height If height doubles and base remains unchanged then Area=2×base×height If height triples then Area=3×base×height If height is 100 times the original then Area=100×base×height

Value is 3 - √8

Step-by-step explanation:

$x = 3 + \sqrt{8} \\ \\ \frac{1}{x} = \frac{1}{3 + \sqrt{8} } \\$

rationalise the denominator:

$= \frac{1}{3 + \sqrt{8} } . \frac{3 - \sqrt{8} }{3 - \sqrt{8} } \\ \\ = \frac{3 - \sqrt{8} }{ {3}^{2} - {( \sqrt{8}) }^{2} } \\ \\ = \frac{3 - \sqrt{8} }{9 - 8} \\ \\ = 3 - \sqrt{8}$
