From the Given Diagram, in Which Abcd is a Parallelogram, Abl is a Line Segment and E is Mid-point of Bc. Then, we can solve the problem as shown below: mAB = m DC 9x -14 = 3x + 4 Transpose and combine same term: 9x - 3x =4 +14 6x= 18 x=3 Solving for DC: DC = 3X + 4 DC = 3(3) + 4 DC = 13 units. Question Papers 10. 19 in. Prove that (i) ar (ABCD) = ar (EFCD) Given that ABCD is a parallelogram Hence AB ∥ CD We know that a rectangle is also a parallelogram, so EFCD is also a parallelogram So, EF ∥ CD Since AB ∥ CD and EF ∥ CD we can say that EB ∥ CD Now, ABCD & EFDC are two parallelograms with the same base CD and between the same parallels EB & CD ∴ ar (ABCD) = ar (EFCD) Example 1 In Fig., ABCD is a parallelogram … MCQs on Class 9 Areas of Parallelogram & Triangles.
