mubzzBest ResponseYou've already chosen the best response.1
Part 1) coordinates of point A (5, 2) coordinates of point B (4 , 1) Distance formula = \[\sqrt{(x _{2}  x _{1})^{2} +(y _{2}  y _{1})^{2}}\] So your distance between A and B would be \[\sqrt{(5  4)^{2} +(2 + 1)^{2}}\] => \[\sqrt{(9)^{2} +(1)^{2}}\] => \[\sqrt{81 + 1}\] => \[\sqrt{82}\] or 9.05

so 9.05 would be the answer and it is already rounded to 2 decmial points?

Part 2) Part 1) coordinates of point A ( 11, 4) coordinates of point B ( 8 , 8) Distance formula = \[\sqrt{(x _{2}  x _{1})^{2} +(y _{2}  y _{1})^{2}}\] So AB is 5 units  coordinates of point C ( 3, 2) coordinates of point D ( 7 , 2) Distance formula = \[\sqrt{(x _{2}  x _{1})^{2} +(y _{2}  y _{1})^{2}}\] So CD is 10.7703  Divide length of CD by length of AB 10.7703/5 = 2.15406 rounded to 2 decimal places, this is 2.15 times longer

In order to calculate midpoint, \[Midpoint (x , y) = (x _{1} + x _{2})/2 , (y _{1} + y _{2})/2\] Midpoint = (12+ 4)/2 , (7 + 7)/2 midpoint = (4 , 0)

For 2.png, when you have to calculate the midpoint of TS, Midpoint(x,y)=(x1+x2)/2,(y1+y2)/2 Midpoint = (6+ 3)/2 , (4 + 2)/2 midpoint = (1.5 , 1)
