Sure! Let’s solve each problem step by step. The worksheet asks for the
area of different shapes: rectangles, squares, and triangles.
---
🔷 Key Formulas to Remember:
-
Rectangle or Square Area = Length × Width
*(For a square, all sides are equal, so Area = side × side)*
-
Triangle Area = (Base × Height) ÷ 2
*(The height is the perpendicular distance from the base to the opposite vertex — shown as a dashed line in the diagrams)*

✔ Problem-by-Problem Solutions:
---
1. Rectangle: 10m long, 4m wide
>
Formula: Area = length × width
>
Calculation: 10 × 4 =
40 m²
✔ Answer: 40 m²
---
2. Triangle: Base = 9m, Height = 6m
>
Formula: Area = (base × height) ÷ 2
>
Calculation: (9 × 6) ÷ 2 = 54 ÷ 2 =
27 m²
✔ Answer: 27 m²
---
3. Square: Side = 7m
>
Formula: Area = side × side
>
Calculation: 7 × 7 =
49 m²
✔ Answer: 49 m²
---
4. Triangle: Base = 8m, Height = 12m
>
Formula: Area = (base × height) ÷ 2
>
Calculation: (8 × 12) ÷ 2 = 96 ÷ 2 =
48 m²
✔ Answer: 48 m²
---
5. Rectangle: 20m long, 7m wide
>
Formula: Area = length × width
>
Calculation: 20 × 7 =
140 m²
✔ Answer: 140 m²
---
6. Rectangle: 11m long, 8m wide
>
Formula: Area = length × width
>
Calculation: 11 × 8 =
88 m²
✔ Answer: 88 m²
