Question

If abc similar def BC=3cm,EF=4cm,and area of ABC=54cmsqare determine the area of DEF ​

Answer 1

Answer:

ar. (Δdef)=96cm^2

Step-by-step explanation:

the solution is given in above picture.

Here, we have used the area theorem of the similar triangles.

Answer 2

Step-by-step explanation:

If bc =3 and ef=4

A(ΔABC)=54

divide by A(ΔDEF )

54/A(ΔDEF)=3/4

=54/3

=18
