Question

How do I solve this?

Answer 1

notice the picture below

due to equal sides on each scalene triangle, the angle bisector cuts the horizontal in half

thus, use the pythagorean theorem to get the "b" or opposite side


`\bf c^2=a^2+b^2\implies √(c^2-a^2)=b`

also notice, that "b" is also the altitude or height "h"

what's the area? well, area of a triangle is 1/2 bh
get the area of each triangle and sum them up, that's the area of the kite
