PLZ HELP ME (PICTURE OF PROBLEM)
1 answer:
AB = 7 1/2
BC = 2 1/4
DE = 1 1/4
AB = GH + EF + CD
AH + FG = DE + BC
The perimeter is AB + BC + CD + DE + EF + FG + GH + HA.
AB + BC + CD + DE + EF + FG + GH + HA =
= AB + BC + DE + AB + DE + BC =
= 2AB +2BC +2DE =
= 2 · 7 1/2 + 2 · 2 1/4 + 2 · 1 1/4 =
= 15 + 4 2/4 + 2 2/4 =
= 15 + 4 1/2 + 2 1/2 =
= 19 1/2 + 2 1/2 =
= 22 [m]
