Someone help me how to do it and write the answer or just write the answer
please and thanks

The total perimeter of the triangle, rounded to the nearest tenth, is 37.5 units.

Step-by-step explanation:

You can answer this simply by applying the Pythagorean theorem to each side, finding each side's length and then adding them up.

The top side goes from -8x7 to 6x3, so so the change on the x axis is 6 - (-8), or 14, and on the y axis it's 7 - 3, or 4.

That means that the top side has a length of:

Similarly with the right side, we have a Δy of 7 and a Δx of 4:

And with the remaining side:

Now we can just sum up those three numbers to get the approximate perimeter:

14.6 + 14.9 + 8.1

= 29.5 + 8.1

= 37.6

Now that matches none of the answers given, but is very close to answer C.  The difference here happens because of where rounding is done.  I rounded to the nearest tenth on every side length, but they rounded on the end result.

if you need just tell me and i will come to the rescue.
