Worked Solution & Example Answer:Calculate the total length of the wall on the eastern side of the building - NSC Civil Technology Civil Services - Question 2 - 2020 - Paper 1
Step 1
Calculate the total length of the wall on the eastern side of the building
Answer
To find the total length of the wall on the eastern side, we need to sum all the relevant dimensions indicated in the drawing.
Given the dimensions:
- The length of the eastern wall includes the following:
- Length from the corner of Bedroom 2 to the corner of the building (3 000 mm)
- Width of Bedroom 2 (2 000 mm)
- Width of the toilet (110 mm)
- Width of the bathroom (2 000 mm)
The calculations would be:
- Convert all measurements to metres:
- 3 000 mm = 3.00 m
- 2 000 mm = 2.00 m
- 110 mm = 0.11 m
- Total length = 3.00 + 2.00 + 0.11 + 2.00 = 7.11 m
Thus, the total length of the wall on the eastern side of the building is 7.11 metres.
Step 2
Verify the calculation
Answer
Alternatively, the total length can also be calculated by breaking down each segment accordingly and confirming:
- Bedroom 2: 3 000 mm = 3.00 m
- Width of toilet: 110 mm = 0.11 m
- Width of bathroom: 2 000 mm = 2.00 m
The total length calculation again gives:
total length = 3.00 + 0.11 + 2.00 = 5.11 m
If more walls are considered per the layout, ensure they are included in the total.
