For example:

√4 = 2

√16 = 4

√64 = 8

etc

Answer:

38.5 m²

Step-by-step explanation:

$A=\frac{1}{2}bh$ when $b$ is the base length of the triangle and $h$ is its height

Plug in the base length, 11 m and the height, 7 m

$A=\frac{1}{2}(11)(7)\\A=\frac{1}{2}(77)\\A=38.5$

Therefore, the area of the figure is 38.5 m².

I hope this helps!

I WILL MARK BRAINLIEST!!! 25 POINTS!!! Select ALL of the correct systems of equations.

choli [55]

The 3rd and 5th systems of equations are the answer.

Point A is at (3,-1), so all you do is input 3 for x and -1 for y into all the equations. For the systems to work, both equations must work with (3,-1).

Only the third and fifth boxes work.
