The correct Answer is:
To find the area of triangle BDE given that the area of triangle ABC is 44 cm², and D and E are midpoints of sides BC and AB respectively, we can follow these steps: ### Step 1: Understand the triangle and midpoints We have triangle ABC with area 44 cm². D is the midpoint of side BC, and E is the midpoint of side AB. **Hint:** Remember that midpoints divide the segments into equal halves. ### Step 2: Divide triangle ABC into two smaller triangles Since D is the midpoint of BC, line AD divides triangle ABC into two smaller triangles: ABD and ACD. Because D is the midpoint, the areas of triangles ABD and ACD are equal. **Calculation:** Area of triangle ABD = Area of triangle ACD = Total area of triangle ABC / 2 Area of triangle ABD = 44 cm² / 2 = 22 cm² **Hint:** When a line is drawn from a vertex to the midpoint of the opposite side, it divides the triangle into two triangles of equal area. ### Step 3: Analyze triangle ABD Now, we focus on triangle ABD. E is the midpoint of side AB. Therefore, line segment DE divides triangle ABD into two smaller triangles: ADE and BDE. Since E is the midpoint, triangles ADE and BDE also have equal areas. **Calculation:** Area of triangle ADE = Area of triangle BDE = Area of triangle ABD / 2 Area of triangle BDE = 22 cm² / 2 = 11 cm² **Hint:** Midpoints also divide the area of triangles into equal parts. ### Step 4: Conclusion Thus, the area of triangle BDE is 11 cm². **Final Answer:** The area of triangle BDE is 11 cm².
