We know that
see the picture to better understand the problem
in the right triangle ABC
Applying the Pythagoras Theorem
AB²=BC²+AC²-------> BC²=AB²-AC²
AB=8 ft
AC=4 ft
BC²=8²-4²-----> BC²=48--------> BC=√48-------> BC=6.93 ft
the answer is6.93 ft
Let, the original price = x
x*20 /100 = 27
x = 2700/20 = 135
Original price was $135
The answer is 16.27 rounded to the nearest hundredth
