To find the area of a rectangle or square, you multiply the length by the width. The formula is:
Area = Length × Width
Let’s solve each problem step by step:
---
Problem 1:
Rectangle with sides 5 in and 9 in.
Area = 5 × 9 =
45 in²
---
Problem 2:
Square with sides 10 cm and 10 cm.
Area = 10 × 10 =
100 cm²
---
Problem 3:
Square with sides 22 m and 22 m.
Area = 22 × 22 =
484 m²
*(Check: 20×20=400, 2×20=40, 2×20=40, 2×2=4 → 400+40+40+4=484)*
---
Problem 4:
Rectangle with sides 7 km and 3 km.
Area = 7 × 3 =
21 km²
---
Problem 5:
Square with sides 2 ft and 2 ft.
Area = 2 × 2 =
4 ft²
---
Problem 6:
Rectangle with sides 4 mm and 6 mm.
Area = 4 × 6 =
24 mm²
---
Problem 7:
Square with sides 9 yd and 9 yd.
Area = 9 × 9 =
81 yd²
---
Problem 8:
Rectangle with sides 1 cm and 2 cm.
Area = 1 × 2 =
2 cm²
---
All calculations are verified.
Final Answer:
45, 100, 484, 21, 4, 24, 81, 2
