Find the area of the parallelogram

slava [35]

Answer:

A = 864 cm

Step-by-step explanation:

Since the parallelogram looks like a trapezoid, I'm going to use that area formula.

The area of a trapezoid can be found with A = (a + b) h/2. So, substitute in the given values. A = (9 x 24) 8/2. A = 216 x 8/2. A = 864.

How would you solve this equation? It uses logarithms.

slega [8]

$\bf log_{{ a}}\left( x^{{ b}} \right)\implies {{ b}}\cdot log_{{ a}}(x)\\\\
-----------------------------\\\\
2^{x+1}=5^{2x-1}\implies log(2^{x+1})=log(5^{2x-1})
\\\\\\
(x+1)log(2)=(2x-1)log(5)\implies (x+1)\cfrac{log(2)}{log(5)}=(2x-1)
\\\\\\
now\quad \cfrac{log(2)}{log(5)}\textit{ is just a constant about }0.43068$

and you can simply solve that for "x"
