Hello there.

<span>How to solve the area of triangles?
</span>
Answer: It is actually quite a simple process.
You need to multiply the base by the height.
This part is similar to finding area if squares
There is one extra step though.
You need to divide the number you get by 2.
That's all there is to it.

Example: A triangle has a base of 2cm and a height of 3cm. Find the area:
2 x 3 = 6
6/2 = 3.
The area would be 3cm².

The formula for this is: A = $\frac{1}{2}$ bh

Hope This Helps You!
Good Luck Studying ^-^

Account A and Account B both have a principal of $2,000 and an annual interest rate of 2%. No additional deposits or withdrawals

Answer:

Account B earns more interest.

After 20 years, account B will have earned $171.89 more.

Step-by-step explanation:

Let's calculate the total for each account.

Account A:

Account A earns simple interest. We know that the principal value is $2000 and the interest rate is 2% or 0.02. We can use the simple interest formula:

$A=P(1+rt)$

Where A is the future value, P is the principal, r is the rate, and t is the time in years.

So, let's substitute 2000 for P, 0.02 for r, and 20 for t. This yields:

$A=2000(1+0.02(20))$

Multiply and add:

$A=2000(1+0.4)=2000(1.4)$

Multiply. So, the total amount of money in Account A after 20 years is:

$A=\$2800$

Since we initially deposited $2000 and our total is now $2800, this means that we earned an interest of $2800-2000=\$ 800$

Account B:

Account B earns compound interest. Like Account A, Account B has a principal value of $2000 and the interest rate is 2% or 0.02. We also know that it's compounded annually, so once per year. We can use the compound interest formula:

$B=P(1+\frac{r}{n}})^{nt}$
