Math worksheet for calculating the area of rectangles using decimal measurements.

Let's solve each problem step by step. The area of a rectangle is calculated using the formula:

$$
\text{Area} = \text{length} \times \text{width}
$$

We'll apply this formula to each rectangle, making sure to multiply the given decimal dimensions correctly.

1)

- Length = 7.1 in
- Width = 16.6 in
$$
\text{Area} = 7.1 \times 16.6 = ?
$$
$$
7.1 \times 16.6 = (7 \times 16.6) + (0.1 \times 16.6) = 117.2 + 1.66 = 118.86 \text{ in}^2
$$
✔ Area = 118.86 in²

---

2)

- Length = 11.3 ft
- Width = 5 ft
$$
\text{Area} = 11.3 \times 5 = 56.5 \text{ ft}^2
$$
✔ Area = 56.5 ft²

---

3)

- Length = 8.2 yd
- Width = 2.9 yd
$$
\text{Area} = 8.2 \times 2.9 = ?
$$
Break it down:
$$
8.2 \times 2.9 = (8 \times 2.9) + (0.2 \times 2.9) = 23.2 + 0.58 = 23.78 \text{ yd}^2
$$
✔ Area = 23.78 yd²

---

4)

- Length = 17.8 yd
- Width = 3.9 yd
$$
\text{Area} = 17.8 \times 3.9 = ?
$$
$$
17.8 \times 3.9 = (17 \times 3.9) + (0.8 \times 3.9) = 66.3 + 3.12 = 69.42 \text{ yd}^2
$$
✔ Area = 69.42 yd²

---

5)

- Length = 12.4 in
- Width = 10.5 in
$$
\text{Area} = 12.4 \times 10.5 = ?
$$
$$
12.4 \times 10.5 = (12 \times 10.5) + (0.4 \times 10.5) = 126 + 4.2 = 130.2 \text{ in}^2
$$
✔ Area = 130.2 in²

---

6)

- Length = 7.7 ft
- Width = 9.7 ft
$$
\text{Area} = 7.7 \times 9.7 = ?
$$
$$
7.7 \times 9.7 = (7 \times 9.7) + (0.7 \times 9.7) = 67.9 + 6.79 = 74.69 \text{ ft}^2
$$
✔ Area = 74.69 ft²

---

7)

- Length = 14.9 ft
- Width = 6.4 ft
$$
\text{Area} = 14.9 \times 6.4 = ?
$$
$$
14.9 \times 6.4 = (14 \times 6.4) + (0.9 \times 6.4) = 89.6 + 5.76 = 95.36 \text{ ft}^2
$$
✔ Area = 95.36 ft²

---

8)

- Length = 13.6 yd
- Width = 5 yd
$$
\text{Area} = 13.6 \times 5 = 68 \text{ yd}^2
$$
✔ Area = 68 yd²

---

9)

- Length = 15.5 in
- Width = 4.2 in
$$
\text{Area} = 15.5 \times 4.2 = ?
$$
$$
15.5 \times 4.2 = (15 \times 4.2) + (0.5 \times 4.2) = 63 + 2.1 = 65.1 \text{ in}^2
$$
✔ Area = 65.1 in²
