Since they are similar, that means they are proportionally the same. So KL is similar to PN JL is similar to PM
So, You need to find how much bigger is the second triangle from first. It is proportionally scaled up.
KL/JL = PN/ PM
You basically put in order of triangles. Left triangle on left side of equal sign and right triangle on right side of equal sign. You put in denominator the similar sides and numerator the similar sides (the side that is similar to the side of the other triangle)
