We know that the formula for the Area, A of a triangle is given as:
.....(Equation 1)
In our question we already know that and
Substituting these values in (Equation 1) we will get:
Multiplying both sides by 2 we will get:
In-order to find base we will isolate it by dividing both sides by 15. Thus, we get:
Thus, the answer is, base=27 mm.

Problem 2
<h3>Answer: Average rate of change = 4</h3>==========================================================
Explanation:
When we have an interval [a,b], the average rate of change over this interval is given by the formula
You probably can notice that we have something that looks eerily similar to the slope formula. That's because average rates of change are basically the same as the slope of the straight line through the endpoints of the interval. The f(b)-f(a) is the change in y of f(x) outputs. The b-a down below is the change of x values when going from x = a to x = b.
-------------------
Let's evaluate the function at x = 1
f(x) = x^2+1
f(1) = 1^2+1
f(1) = 2
Repeat for x = 3
f(x) = x^2+1
f(3) = 3^2+1
f(3) = 10
--------------------
We have enough info to evaluate the original formula I mentioned earlier
The average rate of change on this interval is 4
This is the same as saying the slope of the line through (1,2) and (3,10) is m = 4
See the graph below.
