1. The problem statement, all variables and given/known data

the formula of a triangle is b2/2, so the integral should be b3/6, right? Well, that can't be right. Because if the base of the triangle is 4, it's area will not add up to 8. What am I doing wrong?

The problem is find the area of a triangle with base 4 using integration.

noobilly

(b^2)/2 is the area of the triangle - thats the formula you should get after you do the integration, not before. just think of integration as finding the area under the line
