Given:
A shed with a pent roof needs to have some new roof beams fitted. the width of the shed is 5m and the height of the pent roof is 1.3 m
To find:
Work out the length of the roof beams needed to be 1dp
Solution:
From given, we have,
The width of the shed is 5m and the height of the pent roof is 1.3 m
The length, width and the height of the root forms a right-angled triangle.
Therefore, the length of the roof beam needed is given by,
Length² = Wdith² + Height²
Length² = 5² + 1.3²
Length² = 25 + 1.69
Length² = 26.69
Length = 5.167 m
Therefore, the length of the roof beams needed is 5.167 m
