Answer
To calculate the area of roof tiles needed, we first determine the dimensions of the roof. The total area is calculated as:
Area = length × width
Given:
Length (L) = 8,740 mm
Width (W) = 3,600 mm + 50 mm (overhang) = 3,650 mm
Therefore,
Area = 8,740 mm × 3,650 mm = 31,912,000 mm²
To convert to square meters:
Area = 31,912,000/1,000,000 = 31.912 m²
Round off to 31.9 m².

Answer
To find the number of roof trusses, we use the following dimensions:
The internal dimension is 8,000 mm. The centre-to-centre spacing between the roof trusses is 500 mm. The calculation would be:
Number of trusses = Internal dimension / Centre-to-centre spacing + 1
Number of trusses = 8,000 mm / 500 mm + 1 = 16 + 1 = 17 trusses.
