If the diagonal of a square is approximately 12.73, what is the length of its sides?

Alja [10]

Answer:

The length of the sides of the square is 9.0015

Step-by-step explanation:

Given

The diagonal of a square = 12.73

Required

The length of its side

Let the length and the diagonal of the square be represented by L and D, respectively.

So that

D = 12.73

The relationship between the diagonal and the length of a square is given by the Pythagoras theorem as follows:

$D^{2} = L^{2} + L^{2}$

Solving further, we have

$D^{2} = 2L^{2}$

Divide both sides by 2

$\frac{D^{2}}{2} = \frac{2L^{2}}{2}$

$\frac{D^{2}}{2} = L^2$

Take Square root of both sides

$\sqrt{\frac{D^{2}}{2}} = \sqrt{L^2}$

$\sqrt{\frac{D^{2}}{2}} = L$

Reorder

$L = \sqrt{\frac{D^{2}}{2}}$

Now, the value of L can be calculated by substituting 12.73 for D

$L = \sqrt{\frac{12.73^{2}}{2}}$

$L = \sqrt{\frac{162.0529}{2}}$

$L = \sqrt{{81.02645}$

$L = 9.001469325$

$L = 9.0015$ (Approximated)

Hence, the length of the sides of the square is approximately 9.0015

drek231 [11]

Answer:

400 lira

Step-by-step explanation:

Yukarıdaki sorudan şunu söyleriz: Bir satıcı, sattığı her ürün için satış fiyatının 2 / 9'u kadar kar eder.

Dolayısıyla 1800 liraya televizyon satarsa o televizyondan elde ettiği kâr şöyle hesaplanır:

2/9 × 1800 lira

= 400 lira

Answer:

208 $cm^2$

Step-by-step explanation:

We can find the area of the net by adding up the area of each of the 6 rectangles that make up the net. Since two of each rectangle are the same, we only have to find the area of the 3 different sized rectangles and multiply each by 2.

Rectangle pairs are:

Left rectangle and right rectangle
Top rectangle and the rectangle above the bottom rectangle
Bottom rectangle and the rectangle surrounded by all for sides

Now, let's solve the question.

Left rectangle:

6 x 4 = 24, rectangle has area of 24 squared cm

Top rectangle:

6 x 8 = 48, rectangle has area of 48 squared cm

Bottom rectangle:

4 x 8 = 32, rectangle has area of 32 squared cm

Add up the areas:

(24 x 2) + (48 x 2) + (32 x 2) = 208

The rectangle has a surface area of 208 squared cm

yulyashka [42]

If the 1/3 candy is shared into three equal parts. Then the fraction of the candy bar will each kid get will be 1/9.

<h3>What is division?</h3>

Division means the separation of something into different parts, sharing of something among different people, places, etc.

Alex has 1/3 of a candy bar.

He wants to share what he has left of his candy bar with his 2 friends so that all three of them get equal portions.

Then the fraction of the candy bar will each kid get will be

$\rightarrow \dfrac{1/3}{3}\\\\\rightarrow \dfrac{1}{3\times3}\\\\\rightarrow \dfrac{1}{9}$
