siniylev [52]

Answer:

17852.5$

Step-by-step explanation:

I already answer this in another part, but here it is againa:

In this case, all you need to do is sum all the amounts and take out the down payment of 2500$

First, the car of 18,500 with the 6.5% sale tax, it would be:

18,500 * (6.5/100) = 1202.5$

18500 + 1202.5 = 19702.5$

Now the charge and fees:

450+155+45 = 650$

Then:

19702.5 + 650 = 20352.5$

Finally, the down payment:

20352.5 - 2500 = 17852.5 $

The area of ABCD is 640 cm²

<h3>What is similarity in trapezoid?</h3>

In order for two trapezoids to be similar their corresponding sides must have the same ratio. Since the largest base length in the image is and the corresponding side is , the other base must also be times greater than the corresponding side.

Given:

EF= 5 cm

AB = 20cm

Area of EFGH = 40 sq cm

Now,

As both trapezoid are similar. So, their corresponding sides must have the same ratio

EF/ AB= BC/ FG= CD/ HG= HE/ DA

So,

area (EFGH) : area(ABCD) = (EF/ AB)²

40 : area(ABCD)=  (5/ 20)²

40 : area(ABCD) = 1/16

area (ABCD) =640  cm²

Hence, Area of trapezoid ABCD = 640 cm²
