A square with sides of 15 units each. What would be the area of the square. Consider a square as a combination of two right angled triangles.	Choose the correct choice from the following
A) 100  B) 256  C) 225  D) 81  E) 144

Rationale: a square can be considered as a set of two right angled triangles joined from the hypotenuse . since the sides are 10 units each . the height and base of both the triangles is 10 each . area of a right angled triangle is 1 / 2 * base * height area of both the triangles is 2 * 1 / 2 * base * height . since both triangles are similar . = base * height = 15 * 15 = 225 ans : c
Answer: C
