In order to accumulate enough money for a down payment on a house, a couple deposits $725 per month into an account paying 39 compounded monthly. If payments are made at the end of each period, how much money will be in the account in 5 years?
Type the amount in the account: $ 842.17
(Round to the nearest dollar.)

Look at ∠A, the angle which resides on (1, 3). If we count 5 units down, you find the other endpoint on side AC. Hence, the length of side AC is 5 units. This figure is equal to the height of the graphed triangle.

If we mirror this process with the figure representing the triangle's length, side BC, we get 4 units.

The formula for calculating a triangle's area is . In this context, the base of the triangle is the same as the length. Now, let's plug in the base and the height.

The area of triangle ABC is 10 squared units.
