Area Worksheets - Free Printable

I'll solve each rectangle area problem step by step. The formula for the area of a rectangle is:

Area = length × width

Let me work through each one:

Problem 1:
- Length = 21 in, Width = 4 in
- Area = 21 × 4 = 84 square inches

Problem 2:
- Length = 18 ft, Width = 5 ft
- Area = 18 × 5 = 90 square feet

Problem 3:
- Length = 14 ft, Width = 5 ft
- Area = 14 × 5 = 70 square feet

Problem 4:
- Length = 12 in, Width = 4 in
- Area = 12 × 4 = 48 square inches

Problem 5:
- Length = 19 ft, Width = 9 ft
- Area = 19 × 9 = 171 square feet

Problem 6:
- Length = 11 in, Width = 5 in
- Area = 11 × 5 = 55 square inches

Problem 7:
- Length = 17 ft, Width = 7 ft
- Area = 17 × 7 = 119 square feet

Problem 8:
- Length = 9 ft, Width = 7 ft
- Area = 9 × 7 = 63 square feet

Final Answer:
1. 84 in²
2. 90 ft²
3. 70 ft²
4. 48 in²
5. 171 ft²
6. 55 in²
7. 119 ft²
8. 63 ft²
