The correct Answer is:
To solve the problem step by step, we will follow the instructions provided in the question.
### Step 1: Prepare the Graph Paper
- Use graph paper and ensure that each division on the graph paper represents 0.5 units (as 2 divisions = 1 unit).
**Hint:** Make sure to label the x-axis and y-axis clearly, and mark the origin (0,0).
### Step 2: Plot the Points P and Q
- Plot the point P(3, 2):
- Move 3 units to the right on the x-axis and 2 units up on the y-axis. Mark this point as P.
- Plot the point Q(-3, -2):
- Move 3 units to the left on the x-axis and 2 units down on the y-axis. Mark this point as Q.
**Hint:** Double-check your coordinates by counting the divisions on the graph paper.
### Step 3: Draw Perpendiculars PM and QN on the X-axis
- From point P(3, 2), draw a vertical line straight down to the x-axis. This line will intersect the x-axis at point M(3, 0).
- From point Q(-3, -2), draw a vertical line straight up to the x-axis. This line will intersect the x-axis at point N(-3, 0).
**Hint:** Ensure that the lines are straight and perpendicular to the x-axis.
### Step 4: Identify the Geometric Figure PMQN
- The points P, M, Q, and N form a quadrilateral. Since both PM and QN are vertical lines and MN is horizontal, the shape PMQN is a parallelogram.
**Hint:** Remember that opposite sides of a parallelogram are equal and parallel.
### Step 5: Find the Area of the Parallelogram PMQN
- The area of a parallelogram can be calculated using the formula:
\[
\text{Area} = \text{Base} \times \text{Height}
\]
- Here, the base MN is the distance between points M and N:
- Distance MN = |3 - (-3)| = 6 units.
- The height (the vertical distance from P to the x-axis) is the y-coordinate of point P:
- Height = 2 units.
- Now, calculate the area:
\[
\text{Area} = \text{Base} \times \text{Height} = 6 \times 2 = 12 \text{ square units}
\]
**Hint:** Make sure to use the correct base and height for the area calculation.
### Final Answer
The area of the parallelogram PMQN is **12 square units**.
