Find the area of a rhombus whose side is 25 cm and one of the diagonals is 30 cm? Choose the correct choice from the following
A) 287 sq.cm	B) 655 sq.cm	C) 654 sq.cm	D) 600 sq.cm	E) 266 sq.cm
Consider the rhombus ABCD. Let the diagonals intersect at E. Since diagonals bisect at right angles in a rhombus.   BE2 + AE2 = AB2   252 = 152 + AE2 AE = √(625 - 225)=
