Google maps cartography team is working on improving the scalability quality of maps when you use the app on your phones to zoom in using 4 fingers. They are using a proprietary tool called "MapMaker' to figure out scalability factors. A mathematical model is created for a type of object (below cross-section) to test its scalability on maps app.

In the diagram, `AC = 8 cm, CE = 4 cm` and the area of the triangle BEC is 4.2 sq cm. Another enlargement with centre E, maps `DeltaEBC " onto " DeltaEFA, BC = 3.6 cm`

The area of `DeltaABC` is:

Options

A. 4.2 sq cm
B. 6.3 sq cm
C. 8.4 sq cm
D. 12.6 sq cm
