Question

Given the figures are similar, calculate the perimeter of the ABCDE

Answer 1

both figures are SIMILAR that means their sides share a common ratio or proportion

on the ABCDE figure, we can see the "tick marks" and up and down is 12 and 12
the right-side slanted part is 4 and 4

so what's the left-side AB?

well, we dunno

but using the ration relation between both figures, we can say that
2 on the smaller one, corresponds to AB on the bigger one, as well as
4 on the smaller one, corresponds to 12 on the bigger one, that is BC = 12

or in ratio terms \(\bf \cfrac{2}{AB}=\cfrac{4}{12}\)

solve for AB to find the AB side

sum up all sides in ABCDE and that'd be the perimeter of it

Answer 2

is that it?
