Given :
Height of the ramp, h = 83 cm.
Length of ramp, L = 158 cm.
To Find :
Length of the base of the ramp.
Solution :
Let length of the base is l.
By Pythagoras theorem :
L² = h² + l²
[tex]l=\sqrt{L^2-h^2}\\\\l=\sqrt{158^2-83^2}\\\\l=134.44\ cm[/tex]
Therefore, length of the base is 134.44 cm.
Hence, this is the required solution.
