Question

What is the longest iron rod which can be placed flat across the diagonal of a 4m by 2.5m garden shed floor

Answer 1

4.7m

Explanation:

the length of longest iron rod which can be placed flat across the diagonal of the garden shed can be determined using the Pythagoras theorem,

The Pythagoras theorem : a² + b² = c²

where a = length

b = base

c = diagonal

4² + 2.5² = 22.25²

c =√22,25 = 4.7m
