Area of Rectangle Worksheets - Free Printable

Let’s solve each rectangle area problem step by step.

Remember:
Area of a rectangle = length × width

We’ll multiply the two given sides for each rectangle. Be careful with fractions and mixed numbers!

Problem 1:
Sides: 1 ½ cm and 3 cm
Convert 1 ½ to improper fraction: 3/2
Multiply: (3/2) × 3 = 9/2 = 4 ½ square cm

---

Problem 2:
Sides: 2 ½ ft and 7 ft
Convert 2 ½ to improper fraction: 5/2
Multiply: (5/2) × 7 = 35/2 = 17 ½ square ft

---

Problem 3:
Sides: 3 ½ m and 3 m
Convert 3 ½ to improper fraction: 7/2
Multiply: (7/2) × 3 = 21/2 = 10 ½ square m

---

Problem 4:
Sides: 5 ½ in and 2 in
Convert 5 ½ to improper fraction: 11/2
Multiply: (11/2) × 2 = 22/2 = 11 square in

*(Note: The 2 cancels out the denominator, so it’s just 11)*

---

Problem 5:
Sides: 5 m and ½ m
Multiply: 5 × (1/2) = 5/2 = 2 ½ square m

---

Problem 6:
Sides: 8 cm and 4 ¼ cm
Convert 4 ¼ to improper fraction: 17/4
Multiply: 8 × (17/4) = (8/1) × (17/4) = (8×17)/(1×4) = 136/4 = 34 square cm

*(You can simplify before multiplying: 8 ÷ 4 = 2, then 2 × 17 = 34)*

Final Answer:
1) 4 ½
2) 17 ½
3) 10 ½
4) 11
5) 2 ½
6) 34
