The cross-section of a canal is in the form of a trapezium.If the top ...
Given information:
- Top width of the canal: 15m
- Bottom width of the canal: 8m
- Area of cross-section: 138m
To find: Depth of the canal
Formula:
The area of a trapezium can be calculated using the formula:
Area = (1/2) * (a + b) * h
Where,
a = top width of the trapezium
b = bottom width of the trapezium
h = height or depth of the trapezium
Solution:
1. Given that the top width of the canal is 15m, the bottom width is 8m, and the area of the cross-section is 138m.
2. We can use the formula of the area of a trapezium to find the depth of the canal.
3. Substitute the given values into the formula:
138 = (1/2) * (15 + 8) * h
4. Simplify the equation:
138 = (1/2) * 23 * h
138 = 11.5h
5. Divide both sides of the equation by 11.5:
h = 138 / 11.5
h ≈ 12
Answer:
The depth of the canal is approximately 12 meters.
- Top width of the canal: 15m
- Bottom width of the canal: 8m
- Area of cross-section: 138m
