## anonymous one year ago What is the length of stack M N with bar on top ? Round to the nearest tenth of a unit. http://static.k12.com/calms_media/media/1578500_1579000/1578500/1/88da3ceb29f9eed33d82d83b001cab74fc012268/MS_IMC-150122-130504.jpg

Distance between two points A(x1,y1) and B(x2,y2) is given by possitve $\sqrt{(x1-x2)^{2}+(y1-y2)^{2}}$. So putting values, we get $\sqrt{(8-2)^{2}+(4-(-2))^{2}}=\sqrt{6^{2}+6^{2}}=\sqrt{72}=6\sqrt{2}$

so basically it would be 8.5 @SwapnilP
