Answer:
9.63 metres
Step-by-step explanation:
The base to height ratio =12:1
From the given ramp, Base to Height Ratio =Base:0.8
Therefore:
12:1=Base:0.8
[tex]\frac{12}{1}=\frac{Base}{0.8} \\Base =12 X 0.8=9.6m[/tex]
To find the length of the ramp, we apply Pythagoras theorem in the right triangle formed.
Length of the ramp ,l
[tex]=\sqrt{9.6^2+0.8^2} \\l=9.63\:metres[/tex]
