Question

I NEED HELP ON THIS ASAP!

Answer 1

23.54

Explanation:

Distance Formula:
`√((x_2-x_1)^2+(y_2-y_1)^2)`

We know the perimeter is the sum of all the side lengths of the triangle. Using the distance formula, we get
`√((10-2)^2 + (9-5)^2)` from X to Y,
`√((6-10)^2+(1-9)^2)` from Y to Z, and
`√((6-2)^2 + (1-5)^2)` from Z to X. This equals
`√(80)`
`+√(80) + √(32)`, which equals approximately 23.54

I'm not sure what the previous triangles you calculated the area of were, or how this is different from those examples.

Answer 2

six thousandth

Explanation:

z is a perimeter of one hundredths x is a perimeter of five thousandths add them then estimate to the nearest hundredth and you will get 6 thousadths and that is your answer
