Answer 1

AB= 5 cm
AC= 8 cm
BD = 10 cm
BE = 12 cm
BC = AC -AB
BC= 8 cm -5 cm
BC= 3 cm
CD= BD -BC
CD= 10 cm - 3 cm
CD = 7 cm
DE = BE -BC - CD
DE = 12 cm - 3 cm - 7 cm
DE = 2 cm
CE = CD + DE
CE = 7 cm + 2 cm
CE = 9 cm
AD = AB + BC + CD
AD= 5 cm + 3 cm + 7 cm
AD = 10 cm
AE = AB + BC + CD + DE
AE = 5 cm + 3cm + 7 cm + 2 cm
AE = 17 cm
