Answer 1

Answer:

hope it's helpful for you.

Answer 2

Explanation:

Given:-∆ABC And ∆DEF,BC=3cm,EF=4cm

Area of ∆DEF =54Cm.sq.

Solution:-

A.T.Q.∆ABC is similar to ∆DEF

So, Area of ABC/Area of DEF=(BC)sq./(EF)Sq.

==>54/Area of DEF=(3)sq./(4)sq.

Area of DEF=54×16/9 =96cm.sq.

Hence , Area Of ∆DEF=96cm.sq.
