The area of a trapeziod is found by adding the top and bottom dimensions together, dividing that by 2, then multiplying by the height.

The top half of the window is: 16 +30 = 46/2 = 23 x 276 square inches.

The top and bottom are the same.

Total area = 276 + 276 = 552 in^2

Answer:

552 in^2

Step-by-step explanation:

Area of trapezoid = 1/2(16 + 30(12)

= 1/2(46)(12)

= 276

Two trapezoids are similar

So total area = 2 x 276 = 552 in^2

Plsss help ill give brainiest
Elena L [17]

To solve this problem, we have to use the area of both gauze or the dimensions on each gauze and compare them. we can see that the sheets are not similar as they have different areas.

<h3>Area of Rectangle</h3>

The area of a rectangle is given as the product between the length and it's width.

Data;

  • Length = 9in
  • Area = 45in^2
  • width = ?
  • length 2 = 4in
  • width 2 = 3in

area = length * width

In the first gauze, the area is given as 45in^2 and we have value of the length. To find the width of the first gauze can be calculated as

A = length * width\\width = \frac{area}{length} \\width = \frac{45}{9} \\width = 5in

We can see that the width are not equal so is their length.

But if we would truly compare them, the accurate way to do that is by their area

The area of the second gauze is given by

a = 3 * 4 = 12in^2

From the above calculations, we can see that the sheets are not similar as they have different areas.

The difference of two numbers is 3. Their sum is - 24. Find the numbers.
Katarina [22]

Answer:

y = -13.5

x = -10.5

Step-by-step explanation:

Hi there!

Let the two numbers be equal to <em>x</em> and <em>y</em>.

The difference of two numbers is 3 ⇒ x - y = 3

Their sum is - 24 ⇒ x + y = -24

Solve using elimination:

x - y = 3

x + y = -24

Add the two equations:

x + x - y + y = 3 - 24

2x = -21

x = -10.5

Solve for y:

-10.5 - y = 3

- y = 3 + 10.5

y = -13.5

I hope this helps!
