This is the whole question. I just cant figure out the last part

Step 3
We will now approximate the area using right endpoints. Recall that, using right endpoints, the area A of the
region that lies under the graph of the continuous function v is the limit of the sum of the areas of the n
approximating rectangles as follows.
A = lim R, = lim v(t, JAt + v(t,)at +.

Here we wish to find R, where At = 0.5. Therefore, we have the following.
R = v(t, )(0.5) + v(t,)X(0.5) + v(t,)(0.5) + v(e,)(0.5) + v(e,)(0.5) + vle,M0.5)

We have determined the estimations L = 34.7 and R, = 44.8, where both are measured in feet. We note

We will approximate the area of the shaded region using the method of approximating rectangles. Recall that
this can be done using either the left endpoints or the right endpoints of the subintervals. One will give an
estimate that is smaller than the actual value, and the other will give an estimate that is larger than the actual
value.
In the given table we note that there are six clear subintervals: [0, 0.5], [0.5, 1.0], [1.0, 1.5], [1.5, 2.0],
[2.0, 2.5], and [2.5, 3.0]. The width of each of these subintervals is 0.5
0.5. Therefore, the
change in t over each subinterval, At, can be stated as follows.

Step 2
Recall that, using left endpoints, the area A of the region that lies under the graph of the continuous function v
is the limit of the sum of the areas of the n approximating rectangles as follows.

Here we wish to find L, where At = 0.5. Therefore, we have the following.
4 = v(t,X0.5) + v(t,)(0.5) + v(t,)(0.5) + v(t,)(0.5) + v(t,(0.5) + v(t,X0.5)
