Answer:

h = 10.018 ≈ 10 m

Step-by-step explanation:

Because this triangle is right, there are two ways to get base*height (the area); <em>the two legs, or the hypotenuse and the altitude it is connected to</em>. And those areas will be equal.

Therefore, <em>12 m * 18.2 m = 21.8 m * h</em>.

Multiply: 218.4 = 21.8h

Divide: h = 10.018 ≈ 10 m

x/97 = 200/10000

97*200 = 10,000x

19400 = 10,000x

You can also do it this way:

200/10000 = 0.02

0.02 * 97 = 1.94
