Question

If
AABC - ADEF, AB = 4 cm, DE = 6 cm,
EF = 9 cm and FD = 12 cm, find the
perimeter of AABC.​

Answer 1

Answer:

Also,. AABC - ADEF

AB/ED=BC/EF=AC/DF

4/6 = BC/9 = AC/12

On taking first two terms , we get

4/6 = BC/9

= BC = 4×9/6 = 6cm

= AC = 6×12/9 = 8cm

Now,. perimeter of A abc = AB+BC+AC

= 4+6+8=18cm
