A shed with a pent roof need 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

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
