Question

answer above question step by step ​

Answer 1

Step-by-step explanation:

ratio of area of two ∆s on the same base line and a common vertex is equal to the ratio of the corresponding bases.

(1) Ar ∆ ABD / Ar ∆ ABC = AD / AC

=> (AC - DC) / AC => (16 - 9) / 16 => 7/16

(2) Ar ∆ BDC / Ar ∆ ABC = DC/AC => 9/16

(3) Ar ∆ ABD / Ar ∆ BDC = AD/DC => 7/9
