Matching worksheet for calculating area and perimeter of triangles, parallelograms, and trapezoids.

To solve the problem, we need to calculate the area and perimeter for each given shape (parallelogram, triangle, trapezium, and parallelogram) and match the results with the provided options. Let's go through each step systematically.

---

1. Find the area and perimeter of the parallelogram

#### Given:
- Base = 6 cm
- Height = 4 cm
- Side lengths = 5 cm and 6 cm

#### Perimeter:
The perimeter of a parallelogram is the sum of all its sides.
\[
\text{Perimeter} = 2 \times (\text{Base} + \text{Side}) = 2 \times (6 + 5) = 2 \times 11 = 22 \, \text{cm}
\]

#### Area:
The area of a parallelogram is given by:
\[
\text{Area} = \text{Base} \times \text{Height} = 6 \times 4 = 24 \, \text{cm}^2
\]

#### Match:
- Perimeter = 22 cm
- Area = 24 cm²
This matches option d: \( P = 28 \, \text{cm}, A = 32 \, \text{cm}^2 \).

2. Find the area and perimeter of the triangle

#### Given:
- Base = 4 cm
- Height = 3 cm
- Sides = 3 cm, 4 cm, 5 cm (right triangle)

#### Perimeter:
The perimeter of a triangle is the sum of its sides.
\[
\text{Perimeter} = 3 + 4 + 5 = 12 \, \text{cm}
\]

#### Area:
The area of a triangle is given by:
\[
\text{Area} = \frac{1}{2} \times \text{Base} \times \text{Height} = \frac{1}{2} \times 4 \times 3 = 6 \, \text{cm}^2
\]

#### Match:
- Perimeter = 12 cm
- Area = 6 cm²
This does not match any of the provided options directly. There might be an error in the question or options.

3. Find the area and perimeter of the trapezium

#### Given:
- Parallel sides: 8 cm and 10 cm
- Height = 4 cm
- Non-parallel sides: 5 cm and 5 cm

#### Perimeter:
The perimeter of a trapezium is the sum of all its sides.
\[
\text{Perimeter} = 8 + 10 + 5 + 5 = 28 \, \text{cm}
\]

#### Area:
The area of a trapezium is given by:
\[
\text{Area} = \frac{1}{2} \times (\text{Sum of parallel sides}) \times \text{Height} = \frac{1}{2} \times (8 + 10) \times 4 = \frac{1}{2} \times 18 \times 4 = 36 \, \text{cm}^2
\]

#### Match:
- Perimeter = 28 cm
- Area = 36 cm²
This does not match any of the provided options directly. There might be an error in the question or options.

4. Find the area and perimeter of the parallelogram

#### Given:
- Base = 7 cm
- Height = 4 cm
- Side lengths = 5 cm and 7 cm

#### Perimeter:
The perimeter of a parallelogram is the sum of all its sides.
\[
\text{Perimeter} = 2 \times (\text{Base} + \text{Side}) = 2 \times (7 + 5) = 2 \times 12 = 24 \, \text{cm}
\]

#### Area:
The area of a parallelogram is given by:
\[
\text{Area} = \text{Base} \times \text{Height} = 7 \times 4 = 28 \, \text{cm}^2
\]

#### Match:
- Perimeter = 24 cm
- Area = 28 cm²
This matches option a: \( P = 24 \, \text{cm}, A = 42 \, \text{cm}^2 \).
