Step-by-step explanation:
Because they are similar triangles you can find the scale factor first.
395/553 is the scale factor
(395/553)*280=200
(395/553)*350=250
200+250+395 = 845

Answer:
52 square units
Step-by-step explanation:
For this you need the length of CB and the length of DA.
|CB| = √(10²+2²) = 2√26
|DA| = √(10²+2²) = 2√26
area of ABC = base · height / 2 = 2√26 · 2√26 / 2 = 52
