please answer this question with method and step s please​

Answer 1

Answer:

B is the correct option

Step-by-step explanation:

as BD is the perpendicular bisector,

AD = DC

thus; area of triangle ABC = 1/2 × AC × BD

= 1/2 × (AD + DC) × BD

= 1/2 × (DC + DC) × BD

= 1/2 × (2DC) × BD

= DC × BD

area of triangle ADB = 1/2 × AD × BD

= 1/2 × DC × BD

area of triangle ADB = 2(area of triangle ABC)

therefore;

area of triangle ADB : area of triangle ABC

area of triangle ADB : area of triangle ABC= 1:2.

hope this helps you...
