Answer:
36.00 units
Step-by-step explanation:
Lengths of horizontal and vertical segments are easily determined by subtracting coordinates or counting grid squares:
ST = 6 -1 = 5
TR = 5 -(-1) = 6
IP = 1 -(-6) = 7
PE = 2 -(-3) = 5
The lengths of the diagonal segments are found using the Pythagorean theorem. Those lengths are the root of the sum of the squares of the rise and run. As before, you can determine those from counting squares or subtracting coordinates.
RI = √(2^2 +5^2) = √29 ≈ 5.385
ES = √(3^2 +7^2) = √58 ≈ 7.616
Then the perimeter is the sum of segment lengths:
Perimeter = ST +TR +RI +IP +PE +ES
= 5 + 6 + 5.385 +7 +5 +7.616 = 36.001
Rounded to hundredths, the perimeter is 36.00 units.
Answer:
See Below
Step-by-step explanation:
#17. You just have to plot the points, this should be super easy. Go to the left 6 (because it is negative) then up four. This is M. Then go right 5 and up 4 and plot A.
#18. Point T is a reflection of A over the X-axis. This is quite simple as well. All you need to do it make your Y coordinate negative? Why Y? You'll see. You need to essentially "fold" the graph at the X line, so your Y value goes from up top at 4 to below the X axis as we're reflecting over the X line. I hope that makes sense. T should be at 5,-4
#19 This is the same process as 18, Over the X coordinate. Make Y negative and plot it. It should be H= -6,-4
#20 You can get this from the answers from #18 and #19.
#21. The formula is Base*2+Height*2, or Base+Base+Height+Height. You want the distance around. I'll have you figure this out, but if you get comment and I'll check back. How many steps do you go up from T to A? How about over from H to T 9 or (M to A)? Once you find how many units your base and height are, use the formula for perimeter to find the answer. Hope this helps! :)
