<PRE><B>Question 341236</B>
Area of a triangle is A=b*h/2


You know that the height is 5 times the length of the base:

h = 5b


You also know that the Area is 160 square feet. Put all this info together:


A=b*h/2
160 = b*5b / 2
160 = 5b^2 / 2
320 = 5b^2
64 = b^2
b = 8


So this means the base is 8 feet.


The height is 5 times the base, so it is 40 feet.</PRE>
