If vertices of a triangle are A (5, 0), B (x, y) and C (25, 0), what is its area?

Statement 1: If , y is 10 but x could be -10 or 10. The area is same for x=10 and X= -10 . This is sufficient to answer the question.

Statement 2: If , x=10 but y could be 10 or -10 but different value of y does not affect the area of the triangle. This statement is also sufficient to answer the question.

If vertices of a triangle are A (5, 0), B (x, y) and C (25, 0), what is its area?

Statement (1) ALONE is sufficient, but Statement (2) ALONE is not sufficient Statement (2) ALONE is sufficient, but Statement (1) ALONE is not sufficient BOTH statements TOGETHER are sufficient, but NEITHER statement ALONE is sufficient EACH statement ALONE is sufficient Statements (1) and (2) TOGETHER are NOT sufficient Statement 1: If , y is 10 but x could be -10 or 10. The area is same for x=10 and X= -10 . This is sufficient to answer the question.

Statement 2: If , x=10 but y could be 10 or -10 but different value of y does not affect the area of the triangle. This statement is also sufficient to answer the question.

The correct answer is D.

Formula for triangle |x1(y2-y3)+x2(y3-y1)+x3(y1-y2)|

A (5, 0), B (x, y) and C (25, 0), St 1: Y = 10 X can be -10 or +10 lets try both A (5, 0), B (10, 10) and C (25, 0), | 5(10-0)+ 10(0-0) + 25(0-10)| |50 +0-250|= 200

no lets try X as -10 A (5, 0), B (-10, 10) and C (25, 0),
