Step by Step Solution
The picture below shows the triangle with the base of 5cm and the height of h.
Since the value of the area is given as 20in2, we can substitute A with 30. Similarly, since the base is given as 5cm, we can substitute b with 5. After doing so, we can simplify the equation as shown below:
Now, we have 5h = 40. To find h, we need to remove 5. We can do so by dividing both sides of the equation with 5. This is shown below:
Now, the calculated number 8, has no meaning unless we include the unit for it. Since the area is in inch2, h will be in inch. Hence:
