Answer:
49 units
Step-by-step explanation:
Given the triangles are similar then the ratios of corresponding sides are equal, that is
=
, substitute values
=
( cross- multiply )
22BC = 484 ( divide both sides by 22 )
BC = 22
------------------------------------------------
Similarly
=
, substitute values
=
( cross- multiply )
22AC = 352 ( divide both sides by 22 )
AC = 16
Thus perimeter of Δ ABC is
perimeter = AB + BC + AC = 11 + 22 + 16 = 49 units
