## Homework Statement

## Homework Equations

A=(1/2)w[E+2M]

Where w=width between each interval

E=f(a0)+f(an) is the sum of the end values

M=f(a1)+f(a2)+...f(an-1)

## The Attempt at a Solution

I found the area of the first trapezoidal rule but can't identify the other

w=(15/5)=3metres

E=2.6+2.4=5

M=3+3.2+2.9+2.4=11.5

Therefore, A=(1/2)w[E+2M]=42

I couldn't identify the 2nd one
