Let’s solve each problem one by one. We’ll use the correct area formula for each shape and plug in the numbers carefully.
---
Problem 1: Parallelogram
Base = 6 cm, Height = 5 cm
Area of parallelogram = base × height
→ 6 × 5 =
30 cm²
---
Problem 2: Trapezoid
Top base = 5 cm, Bottom base = 6 cm, Height = 2 cm
Area of trapezoid = (top + bottom) ÷ 2 × height
→ (5 + 6) ÷ 2 = 11 ÷ 2 = 5.5
→ 5.5 × 2 =
11 cm²
---
Problem 3: Rectangle
Length = 8 cm, Width = 5 cm
Area of rectangle = length × width
→ 8 × 5 =
40 cm²
---
Problem 4: Right Triangle
Base = 20 m, Height = 5 m
Area of triangle = (base × height) ÷ 2
→ (20 × 5) ÷ 2 = 100 ÷ 2 =
50 m²
---
Problem 5: Parallelogram
Base = 8 cm, Height = 4 cm
Area = base × height
→ 8 × 4 =
32 cm²
---
Problem 6: Triangle
Base = 8 cm, Height = 4 cm
Area = (base × height) ÷ 2
→ (8 × 4) ÷ 2 = 32 ÷ 2 =
16 cm²
---
Problem 7: Rectangle
Length = 10 in, Width = 4 in
Area = length × width
→ 10 × 4 =
40 in²
---
Problem 8: Triangle
Base = 9 cm, Height = 4 cm
Area = (base × height) ÷ 2
→ (9 × 4) ÷ 2 = 36 ÷ 2 =
18 cm²
*(Note: The “5)” next to it is probably a typo or leftover from another question — we ignore it.)*
---
Problem 9: Trapezoid
Top base = 9 m, Bottom base = 7 m, Height = 6 m
Area = (top + bottom) ÷ 2 × height
→ (9 + 7) ÷ 2 = 16 ÷ 2 = 8
→ 8 × 6 =
48 m²
