Could there be another answer to this? I'm told 62.35 and 62 7/20 are wrong.

Thanks!

does it say to any particular decimal place or significant figure?

in surds form= 36√3cm²

Find the area of triangle ABC if AB = BC = 12 and angle ABC = 120 degrees.

B

12 120 12

A C

Area = (1/2) (12) (12)sin (120) =

72 * sin (120) =

72 * √3 / 2 =

36 √3 units ^2 ≈ 62.35 units^2

Maybe they want the exact value [ first answer ]. ACG

36sqrt3 was right! Thanks you guys!
