hi there.
You have the two sides of a right angled triangle
and you want to find the hypotenuse.
Wall height^2 + ground length^2 = hypotenuse^2
5.2^2 + 1.5^2 = hypotenuse^2
Hypotenuse^2 = 29.29
Hypotenuse = square root of 29.29
Hypotenuse = 5.4m (1 decimal place)
So you need a 5.4m ladder.
Hope this helps.
:-)
