The length of rectangle ABCD is 5 inches and its width is 3 inches. Diagonal AC is divided into three equal segments by points E and F. Find the area of triangle BEF.

class TArea extends RightTriangle

{

triangle t1, t2, t3;

t1.a = a;

t1.c = c/3;

t1.B = B;

t2.a = t1.b;

t2.b = t3.a;

t2.c = c/3;

t2.B = PI - t1.A;

t2.A = PI - t3.B;

t3.c = c/3;

t3.b = b;

t3.A = A;

t1.C + t2.C + t3.C = C;

}

class TArea extends RightTriangle

{

triangle t1, t2, t3;

t1.a = a;

t1.c = c/3;

t1.B = B;

t2.a = t1.b;

t2.b = t3.a;

t2.c = c/3;

t2.B = PI - t1.A;

t2.A = PI - t3.B;

t3.c = c/3;

t3.b = b;

t3.A = A;

t1.C + t2.C + t3.C = C;

}
