    see to solve this question draw a perpendicular on the side b. Now we know that the area of a right angled triangle is \[\frac{ 1 }{ 2 } \times base \times height\] Now we have two triangles with respective base|dw:1347088112276:dw| Now use the area formula. so the area of the truangle A is the combined area of the two triangles. \[A= \frac{ 1 }{ 2 } h \times (b1+b2)\] Now sin(y) is h/c. Replace h from sin(y) using area eqn and you will get the answer as \[\frac{ 2A }{ bc }\]
