**Exercise 9.2 Class 9 Maths Chapter 9 Areas of Parallelograms and Triangles**

**1. In Fig. 9.15, ABCD is a parallelogram, AE ⊥ DC and CF ⊥ AD. If AB = 16 cm, AE = 8 cm and CF = 10 cm, find AD.**

**2. If E,F,G and H are respectively the mid-points of the sides of a parallelogram ABCD, show that ar (EFGH) = 1/2ar (ABCD)**

**3. P and Q are any two points lying on the sides DC and AD respectively of a parallelogram ABCD. Show that ar (APB) = ar (BQC).**

**4. In Fig. 9.16, P is a point in the interior of a parallelogram ABCD. Show that(i) ar (APB) + ar (PCD) = 1/2ar (ABCD)(ii) ar (APD) + ar (PBC) = ar (APB) + ar (PCD)[Hint : Through P, draw a line parallel to AB.]**

**5. In Fig. 9.17, PQRS and ABRS are parallelograms and X is any point on side BR. Show that(i) ar (PQRS) = ar (ABRS)(ii) ar (AX S) = 1/2ar (PQRS)**

**6. A farmer was having a field in the form of a parallelogram PQRS. She took any point A on RS and joined it to points P and Q. In how many parts the fields is divided? What are the shapes of these parts? The farmer wants to sow wheat and pulses in equal portions of the field separately. How should she do it?**
