Transcribed Image Text:**Problem 1:**
Find the perimeter and area of the following parallelogram.
**Diagram Description:**
The given image depicts a parallelogram. It consists of the following measurements:
- The base of the parallelogram is labeled as 20 inches.
- One side (height) is labeled as 5 inches.
- A perpendicular height from the base to the opposite side is shown as a dashed line and is labeled as 4 inches.
**Solution Steps:**
1. **Perimeter:**
- The perimeter of a parallelogram is calculated as the sum of the lengths of all sides.
- Formula: Perimeter = 2(base + side)
- Substitute the given values: Perimeter = 2(20 in + 5 in)
- Calculate: Perimeter = 2(25 in) = 50 inches
2. **Area:**
- The area of a parallelogram is calculated using the base and the corresponding height.
- Formula: Area = base × height
- Substitute the given values: Area = 20 in × 4 in
- Calculate: Area = 80 square inches
The perimeter of the parallelogram is 50 inches, and the area is 80 square inches.
