Question

Figure base length height area
Triangle 2.5 m 14m A
Triangle 10 in B 25 in
Rectangle 17 cm 11 cm C
Parallelogram 4 1/2 ft D 99 ft
10. Box A = ______m² (enter the number only)
11. Box B = ______in (enter number only)
12. Box C = _____cm² (enter number only)
13. Box D = _____ft (enter number only)

Answer 1

To calculate the areas, we'll use the formulas specific to each shape:

1. **Triangle**: Area = (base * height) / 2
2. **Rectangle**: Area = length * width
3. **Parallelogram**: Area = base * height

Now let's solve for each box:

**Box A (Triangle)**
- Base = 2.5 m, Height = 14 m
- Area = (2.5 m * 14 m) / 2 = 35 m²

**Box B (Triangle)**
- Base = 10 in, Height = 25 in
- Area = (10 in * 25 in) / 2 = 125 in²

**Box C (Rectangle)**
- Length = 17 cm, Width = 11 cm
- Area = 17 cm * 11 cm = 187 cm²

**Box D (Parallelogram)**
- Base = 4.5 ft (4 1/2 ft), Height = 99 ft
- Area = 4.5 ft * 99 ft = 445.5 ft²

Now, let's fill in the answers:

10. Box A = **35**
11. Box B = **125**
12. Box C = **187**
13. Box D = **445.5**
