It is just 18 :)It is just 18 :)
I will do Point A carefully, The others I will indicate. Start with the Given Point A. Then do the translations
A(-1,2) Original Point
Reflection: about x axis:x stays the same; y becomes -y:Result(-1,-2)
T<-3,4>: x goes three left, y goes 4 up (-1 - 3, -2 + 4): Result(-4,2)
R90 CCW: Point (x,y) becomes (-y , x ) So (-4,2) becomes(-2, - 4): Result (-2, - 4)
B(4,2) Original Point
- Reflection: (4, - 2)
- T< (-3,4): (4-3,-2 + 4): (1 , 2)
- R90 CCW: (-y,x) = (-2 , 1)
C(4, -5) Original Point
- Reflection (4,5)
- T<-3,4): (4 - 3, 5 + 4): (1,9)
- R90, CCW (-9 , 1)
D(-1 , -5) Original Point
- Reflection (-1,5)
- T(<-3,4): (-1 - 3, 5 + 4): (-4,9)
- R90, CCW ( - 9, - 4)
Note: CCW means Counter Clockwise
The graph on the left is the same one you have been given.
The graph on the right is the same figure after all the transformations
Do 19 x 6 x 2 = 228
then 28 x 19 x 2 = 1064
then 28 x 6 x 2 = 336
<span>then do 228 + 1064 + 336 = 1628</span>
The length is 6/5 of the width, which is 12. so you multiply them, 6/5 times 12/1 and you get 72/5 which simplifies to 14 and 2/5 or 14.4. so your length is 14.4. which means your perimeter is 52.8 inches. and to get the area you just multiply 12 by 14.4 and you get 172.8. so your perimeter is 52.8 and your area is 172.8
B. because I already took the test and you should just trust me GGEZ
