Luiza delivers newspapers in her neighborhood. If you plot the points (-1, 1), (4, 1), (4, -2) and (-1, -2), you will create a representation of the route she takes, in miles. How many miles does her route cover?

Correct answer:

x =  13 mi

Step-by-step explanation:

A=(1,1) B=(4,1) C=(4,2) D=(1,2)  d1=dist(B,A)=(BxAx)2+(ByAy)2=(4(1))2+(11)2=5 d2=dist(C,B)=(CxBx)2+(CyBy)2=(44)2+((2)1)2=3 d3=dist(D,C)=(DxCx)2+(DyCy)2=((1)4)2+((2)(2))2=5  x=d1+d2+d3=5+3+5=13 mi
