Question 590344
if a the altitude of a triangle is decrease by 60% how much does the base increase in order to keep the same area
---------
Decrease by 60% --> 0.4*original h
Area = bh/2
----
Area = (b*c)*(h*0.4)/2 = bh/2
bc(h*0.4) = bh
c = b/0.4 = 2.5b
The base increases by a factor of 2.5
A 150% increase.
