Answer:
Step-by-step explanation:
5/2+3 3/5 + 2 3/4= perimeter of triangle
5/2+18/5+11/4
L.C.M of 2,5 and 4=20
=50/20+72/20+55/20=177/20=8 17/20=8.85 cm
rectangle's perimeter= (7/6+11/4)X2 or 2(7/6+11/4)
=L.C.M of 6 and 4= 12
=(14/12+33/12) X2=47/12 X2= 94/12=7 10/12
177/20>94/12
Hence, the triangle ABE has a greater perimeter.
