If the area of each triangular regions is as shown, what is the area of the polygon?

topjm [15]

For this case, what you must do is add the area of each of the triangles to find the total area of the polygon.
We have then:
A = 2 + 2 + 2 + 2 + 2 + 2 + 2 + 2
A = 16
Equivalently, as the area of each triangle is the same, then:
A = 2 * (8)
A = 16
Answer:
the area of the polygon is:
16

What is the simplified form of StartRoot StartFraction 72 x Superscript 16 Baseline Over 50 x Superscript 36 Baseline EndFractio

aalyn [17]

Answer:

StartFraction 6 Over 5 x Superscript 10 Baseline EndFraction

Step-by-step explanation:

Apparently you want to simplify ...

$\sqrt{\dfrac{72x^{16}}{50x^{36}}}$

The applicable rules of exponents are ...

(a^b)(a^c) = a^(b+c)

1/a^b = a^-b

(a^b)^c = a^(bc)

So the expression simplifies as ...

$\sqrt{\dfrac{72x^{16}}{50x^{36}}}=\sqrt{\dfrac{36}{25x^{36-16}}}=\sqrt{\dfrac{36}{25x^{20}}}\\\\\sqrt{\left(\dfrac{6}{5x^{10}}\right)^2}=\boxed{\dfrac{6}{5x^{10}}}$
