DEF= 6 ft^2

A= 1/2*b*h

Plug in what you know.

6= 1/2*4*h

Multiply like terms.

6=2*h

Divide 2 on both sides.

3=h

If the base of ABC= 12

12/4=3

3*3=9

A= 1/2*b*h
A= 1/2*12*9
A= 1/2*84
A= 42

The area of ABC is 42 ft^2

I hope this helps!

Softa [21]

Answer

Total amount earned after 16 years = $93649

Explanation:

The principal, P = $50,000

Interest rate, r = 4% = 4/100

r = 0.04

The time, t = 16 years

Number of times intesrest is compounded per year, n = 1

Total amount is calculated below:

$\begin{gathered} A=P(1+r)^t \\ \\ A=50000(1+0.04)^{16} \\ \\ A=50000(1.04)^{16} \\ \\ A=\$93649 \end{gathered}$

Total amount earned after 16 years = $93649
