Answer 1

Step-by-step explanation:

Triangle ABC ~ triangle DEF

A(triangle ABC) / A(triangle DEF) = BC^2 / EF^2

Theorem on (Area of similar triangles)

therefore A(triangle ABC) / A(triangle DEF) = 4.8^2 / 7.2^2

= 2^2/ 3^2

= 4 / 9.

Therefore, A(TRIANGLE ABC ) : A(TRIANGLE DEF ) = 4: 9.

Answer 2

(7.2) down of 4.8

(9)down of 4

(9)at last
