Laura bought a square canvas to paint a picture of her cat one side measured 22 centimeters what is tha area of the canvas

Olin [163]

Hi there!

To start, squares are a shape in which all of its sides are congruent to one another. Knowing the length of one side would mean that you would know the length of all the other sides.

Because you know that one side measures 22 cm, you can conclude that all the other sides of the square are also at a length/width of 22 cm.

Next, you will find the area of the square.

Because the area formula is Area=Length * Width, you can easily find the area of the square by multiplying 22*22 since the length and width of any square is the same.

When you simplify 22*22, you should get 484.

Therefore, the area of the square canvas would be 484 cm squared.

Hope this helps and have a marvelous day! :)

Consider that the length of rectangle A is 10 cm and its width is 6 cm. Which rectangle is similar to rectangle A? A) A rectangl

HACTEHA [7]

ANSWER

B) A rectangle with a length of 15 cm and a width of 9 cm.

EXPLANATION

The given rectangle, A, has length, 10cm and its width is 6cm.

The rectangle that is similar to rectangle A, has the corresponding sides in the same proportion.

For option A, the triangle has length 9cm and width 6cm.

The ratio of the corresponding sides are:

$\frac{10}{9} \ne \frac{6}{6}$

Since the ratios are not equal, the two triangles are not similar.

For the triangle in option B, the length is 15cm and the width is 9cm.

The ratio of the corresponding sides are:

$\frac{10}{15} = \frac{6}{9} = \frac{2}{3}$

Since the sides of the triangle are in the same proportion, the two triangles are similar.

For option C, the proportions are not the same.

$\frac{10}{14} \ne \frac{6}{7}$

The proportions are not the same for the triangle in option D.

$\frac{10}{12} \ne \frac{6}{8}$

Forty five men can construct a road 210m long in 60 days. What length would be constructed by 72 men in 50 days assuming that al

blagie [28]

Answer:

280m

Step-by-step explanation:

Work rate would be (210m)/(45people)(60days)=7/90 m/(people)(day)

7/90 m/(people)(day) * 72people * 50days =280m

2x+8y = 6<br> 15x + 20y = 15

Likurg_2 [28]

Answer:

The solution is (0, 3/4)

Step-by-step explanation:

Please copy and share the instructions. Here they are: Solve the following system of linear equations.

Both of the equations can be reduced (simplified):

2x+8y = 6 => x + 4y = 3

15x + 20y = 15 => 3x + 4y = 3

Let's use the elimination by addition and subtraction method. Multiply the first equation by -1, obtaining

-x - 4y = -3

Add the second 3x + 4y = 3

equation to the

first.

We get: 2x = 0.

Thus, x = 0. Substituting 0 for x in the 1st original equation yields:

2(0) + 8y = 6. Then y = 6/8, or y = 3/4.

The solution is (0, 3/4).

The United states currently has 50 states.What fraction of the states had become a part of the United States by 1795? (15) Write

Kryger [21]

Answer:

There are currently 50 states in the United States.

The number of states in 1795 in the United States = 15

Now, the fraction of the states that had become a part of the United States by 1795 is given below:

$\frac{15}{50}=\frac{3}{10}$
