Answer:
Step-by-step explanation:
G is the centeroid of the triangle. G splits AE in the ratio 2 : 1
AG : GE = 2 : 1
AG = 2x and GE = x
2x = 20
x = 20/2
x = 10
GE = 10 ; AG = 20
AE = 20+10 = 30
CG : GD = 2:1
CG = 2x and GD = x
2x = 10
x = 10/2
x = 5
GD = 5
BF = 30
BG : GF = 2 : 1
BG = 2x ; GF = x
BF = 30
BG + GF = 30
2x + x = 30
3x = 30
x = 30/3
x = 10
GF = 10
Answer:220mm
Step-by-step explanation:
22x2=44
64-44=20
length =10mm
10mmx22mm=220mm
C because if you look at it 1 1/4 it passes 2 1/4 so you know it’s gonna be 1 something and 2 1/2 is one after 2 1/4 so to get to 3 1/4 that would be 3 so 1 1/4 is the answer... if that make sense if not I can write it out to you and send a picture of how it’s worked out
