The perimeter of a rectangle is 30meter. If the length is twice the width, what is the width?

Let the length of the rectangle be L and the width be W.

Given that the length is twice the width, Then :

L = 2W .....(1)

But we know that the perimeter is 36.

==> 2L + 2W = 36

==> 2L + L = 36

==> 3L = 36

==> L = 36/3 = 12

==> W = 12/2 = 6

Now we will calculate the area:

==> A = L * W = 12* 6 = 72 square feet.

<span>Then the area of the rectangle is 72 square feet.</span>

<span>I am 100% sure that that would be the answer!!</span>

We know that the sum of measures of internal angles in each quadrangle is 360°.

Look at the picture.

\alpha+\beta+\gamma+\delta=360^o\ \text{and}\ \delta+\tau=360^o\\\\\text{therefore}\\\\\alpha+\beta+\gamma+\delta=\delta+\tau\ \ \ |-\delta\\\\\alpha+\beta+\gamma=\tau

Therefore we have:

\theta=35^o+83^o+23^o=141^o

Answer: θ = 141 deg.

Help<br> =================
Nezavi [6.7K]

Answer:

8 in²

Step-by-step explanation:

The area of a triangle is always base times half height. Since this triangle has a 90° corner, the vertical 4 inch is also the height.

So area is 4*4/2 = 8

Center: (-2,5), radius:7
Firlakuza [10]

Answer:

(x + 2)² + (y - 5)² = 7²

Step-by-step explanation:

Incomplete question.  I believe you meant, "write the equation of the circle with center at (-2, 5) and radius 7.

That would be:

(x + 2)² + (y - 5)² = 7²

Use the marginal revenue and marginal cost curve from the theory of clubs to explain why the NFL has 32 teams while the Bundesli
S_A_V [24]

Answer:

There several reasons why German soccer league has fewer number of team as compared to US NFL, which has 32 teams and the reasons are explained below.

Step-by-step explanation:

• Germany is a smaller in size as compare to US; the revenue from adding new groups into the league is smaller in quantity than the United States. This indicates that income generation by adding an extra team is a smaller in amount than in USA.

• With less income being generated this would mean Germany will have fairly less profit as compared to the USA

• Hence, the top range of groups is inferior in European nation than the US.
