    but it only asks what the perimeter is for BRAIN . and what do i put in for y ? i can't just add y with the numbers .

    Maybe you have to make some sort of ratio if we assume they are similar shapes

    equate 2x+1=12.5, 14z=7.5, 5+y=4.5, that should help you out

    yes i thought of that but 10 does not = 4 nor does 7.5 = 3

    add up all the sides. ANd use pythogorean theorom where necessary to get a side.
