Best ResponseYou've already chosen the best response.2Counting up from 2 \(rightarrow\) to 7, or even from 4 \(\rightarrow\) to 2, how many steps is that?

Best ResponseYou've already chosen the best response.2dw:1439023205596:dw We can use the distance formula to find the distances of x and y. \[x=\sqrt{(2(8))^2+(72)^2}\]\[y=\sqrt{(25)^2+(71)^2}\] After finding x and y, just multiply them together. \[A=x\cdot y\]
