We have to find △△ ABE's perimeter

Given in ΔABEΔABE,

AB=52cm,BE=234em,AE=335cmAB=52cm,BE=234em,AE=335cm

We know, the perimeter of ΔABE=AB+BE+AEΔABE=AB+BE+AE

=(52+234+335)cm=(52+114+185)cm=(50+55+7220)cm=17720cm=(52+234+335)cm=(52+114+185)cm=(50+55+7220)cm=17720cm

Thus, the perimeter of ΔABEΔABE is 8<
