Show Answer Key & Explanations Step-by-step solution for: Finding Length or Width of a Rectangle from Area Worksheets
Absolutely! Let’s solve each problem step by step.

The area of a rectangle is calculated using the formula:

> Area = Length × Width

In problems 1–4, since the rectangles are drawn on a grid and no units are given, we assume each small square is 1 cm × 1 cm, so the area is just the number of squares inside the rectangle.

---

Problem 1:


- The rectangle is 5 squares wide and 4 squares tall.
- Area = 5 × 4 = 20 square cm

Answer: 20

---

Problem 2:


- The rectangle is 3 squares wide and 4 squares tall.
- Area = 3 × 4 = 12 square cm

Answer: 12

---

Problem 3:


- The rectangle is 6 squares wide and 3 squares tall.
- Area = 6 × 3 = 18 square cm

Answer: 18

---

Problem 4:


- The rectangle is 7 squares wide and 4 squares tall.
- Area = 7 × 4 = 28 square cm

Answer: 28

---

Problem 5:


- This rectangle has labeled sides: 5 cm (length) and 3 cm (width).
- Area = 5 × 3 = 15 square cm

Answer: 15

---

Problem 6:


- This is a square (a special rectangle) with all sides 4 cm.
- Area = 4 × 4 = 16 square cm

Answer: 16

---

## Final Answers:

1) 20
2) 12
3) 18
4) 28
5) 15
6) 16

💡 Tip:


When counting squares, you can also think of it as rows × columns — that’s the same as length × width!
