Best ResponseYou've already chosen the best response.1The figures are similar which means that each side of the smaller figure is multiplied by some number to get the length of the corresponding side in the larger figure eg: AB is multiplied by some number k to get the length of JK dw:1440105113878:dw AB*k = JK 3*k = 4.2 what is the value of k ?

Best ResponseYou've already chosen the best response.1yes you can also set up a proportion identify a pair of corresponding sides (one pair has LM = x in it) CD corresponds to LM BC corresponds to KL so we have this proportion CD/LM = BC/KL 4/x = 1/1.4 then solve for x
