Answer to Problem 19PPE
The function rule for area of the triangle is
Area of the triangle when its height is 6 cm is 99 cm2
Explanation of Solution
Given information: The base of the triangle is 3 cm greater than 5 times its height.
Calculation:
Let h cm be the height of the triangle .
The base of the triangle is 3 cm greater than 5 times its height, that is
Then area of the triangle is
Therefore, the function rule for area of the triangle is
where h is height of the triangle in cm.
Now, area of the triangle when its height is 6 cm is
