15 and 24 are the legs of the right triangle, so they are your a and b.

15^2 + 24^2 = c^2

225 + 576 = c^2

801 =c^2

square root of 801 = 28.3

<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

Riley is saving up to buy a new television. She needs a total of $1,049.77. Riley has saved $200.79 already and earns $77.18 per

Xelga [282]

11 weeks are required for Riley to work to save enough money to buy the new television

<h3><u>Solution:</u></h3>

Given that Riley needs a total of $1,049.77

Riley has saved $200.79 already and earns $77.18 per week at her job

To find: Number of weeks Riley need to work to save enough money to buy the new television

Remaining amount needed = $1,049.77 - $200.79

Remaining amount needed = $ 848.98

Let "n" be the number of weeks Riley need to work to save enough money to buy the new television

Also she earns $77.18 per week at her job

1 week ⇒ $ 77.18

"n" weeks ⇒ $ 848.98

Therefore, by cross multiplication,

$n \times 77.18 = 1 \times 848.98\\\\n = \frac{848.98}{77.18}\\\\n = 11$

Therefore 11 weeks are required for her to work to save enough money to buy the new television

<h3><u>Method 2:</u></h3>

<em>Total amount = amount already saved + ($77.18 per week at her job)("n" weeks)</em>

1,049.77 = 200.79 + (77.18)(n)

1049.77 - 200.79 = 77.18n

848.98 = 77.18n

$n = \frac{848.98}{77.18}$

n = 11

Therefore 11 weeks are required for her to work to save enough money to buy the new television
