 
Hi, I drew a rough sketch of the garden with the bisecting line. $AB = 250$ feet, $BC = 200$ feet, $CA = 300$ feet and $D$ is the midpoint of $CA.$ In problems involving triangles you quite often have to use the Law of Sines or the Law of Cosines. Looking at the triangle $ABD,$ you know the lengths of $AB$ and $DA$ and hence if you knew the measure of the angle $DAB$ you could use the Law of Cosines to find the length of $BD.$ Can you use what you know about the triangle $ABC$ to determine the measure of the angle $DAB?$ Penny
