this is the correct answer and helpful for you
Answer:
1.5 sq cm.
Explanation:
The area of the triangle formed by joining the midpoints of the sides of any triangle ABC is (1/4) times the area of the triangle ABC.
In this question, the area of the triangle = (1/2) x product of perpendicular sides = (1/2) x 3 x 4 = 6 sq cm.
Thus, area of the required triangle = (1/4) x 6 = 1.5 sq cm.
