ABCD is a square with each side lenght 1 .Suppose BPC is an equilateral triangle ,find the area if the triangle BPD ...

Answer 1

As = 1 * 1 = 1 sq. unit. = Area of the
sq.

The 2 diagonals divide the sq. into 4
congruent triangles. The area of each triangle = 1/4 of total area:

A = As/4 = 1/4 sq. units = BPC and BPD.
