Let’s solve each problem one by one.
To find the area of a rectangle, we multiply its length by its width.
Area = length × width
We’ll do this for all 8 problems.
---
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
