I need to find the area<br><br><br>there are 3 rectangles and a trapezoid <br><br>show how plz
Evgesh-ka [11]
The area of a rectangle is length x width. We can find the 3 areas of the rectangles with this formula:

20 x 5 = 100
100 yd²

15 x (20-14) = 90
90 yd²

14 x 10 = 140
140 yd²

The area of a trapezoid is 1/2(b1+b2)h
In this problem:

b1=25-15-5
b1=5
b2=10
h=20-14
h=6

We can then plug this into the formula:

A = 1/2(5+10)(6)
A = 1/2(15)(6)
A = 45 yd²

We can then get the area of the whole polygon by adding up the areas of the three rectangles and trapezoid:

A = 100+90+140 + 45
A = 375 yd²

As an incoming college freshman, Tina received a 10-year $9,900 Federal Direct
Ksju [112]

The amount charged on the loan which is the loan interest rate, increases as the time after the initial amount is credited into the account increases.

  • The interest on the Federal Direct Unsubsidized Loan after 4 years 6 months is <u>$1,911.195</u>

Reasons:

The given parameter are;

Loan amount, the principal, P = $9,900

Duration of the loan = 10 years

Loan interest rate, R = 4.29%

Required:

The amount of interest that will accrue while she is still in school and over the 6-months grace period for the freshman loan.

Solution:

Based on a similar question on an online source, we have;

Interest, I = P × R × T

Where;

T = The time = The time the freshman is in school + 6 months

Therefore, normally, we have;

T = 4 years + 6 months = 4.5 years

R = 4.29% = 0.0429

Therefore;

Interest, I = 9,900 × 0.0429 × 4.5 = 1911.195

The interest that will accrue while she is still in school and over the 6-months grace period for the loan,<em> I</em> = <u>$1,911.195</u>
