1) 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 1.3m. Work out the length of the roof beams needed to 1dp.
Answers
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 form 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
Lenth = 5.167 m
Therefore, the length of the roof beams needed is 5.167 m

The length, width and the height of the root form a right-angled triangle.
Therefore, the length of the roof beam needed is given by,
Hypotenuse² = Base² + Perpendicular²
Hypotenuse² = 5² + 1.3²
Hypotenuse² = 25 + 1.69
Hypotenuse² = 26.69
Hypotenuse = 5.167 m
Therefore, the length of the roof beams needed is 5.167 m
