If a triangle has a height of 14 inches and a base of 9 inches, what is its area?

The formula for area of a triangle is 

Area= 1/2*base*height

If you substitute values in for the base and height, you get the equation

Area = 1/2*14*9

When you multiply 1/2 by 14, you get 7.  Substitute for this in your equation.

Area=7*9

Simplify by multiplying 7*9=63.

The area of the triangle is 63 inches.

Here’s the answer. you’re supposed to use 2900 times the interest rate and then add your original amount of money. now you get 2997.15
