31 and 15
31+15=46
31-15=16
The formula for the area of a square is:
A=s²
Since we known that the area is 81ft², we can solve for the length of a side.
A=s²
81=s²
find the square root of both sides
9ft=s
The length of each side is 9ft

Therefore:
12:1=Base:0.8
To find the length of the ramp, we apply Pythagoras theorem in the right triangle formed.
Length of the ramp ,l
