The length of a rectangular deck i 4 time it width, and it perimeter i 20ft , what the deck area?

Answers

Answer 1

The area of rectangular deck with length 8 feet and width 2 feet is 16 ft².

What is area of rectangle ?

Area can be defined as the amount of space covered by a plane of a particular shape. It is measured in "number" of square units (cm², inch², ft² etc.). In other words, the space occupied around this shape is called the area of the rectangle.

Rectangle perimeter = 2(length + width)Rectangle area = length x width

We have, a rectangular deck with

length is 4 times its width and perimeter is 20ft.

Let us assume that "l" and "w" be length and width of a rectangular deck.

so, l = 4 w --(1)

Now, perimeter of rectangular deck = 2 ( l+w)

=> 2(l+w) = 20 --(2)

we have to calculate the area of rectangular deck and for this we have to calculate measure of length and width.

plug the value of "l" in equation (2) from (1)

2(l+w) = 20

=> 2(4w + w) = 20

=> 2× 5w = 20

=> w = 20/10 = 2 feet

from equation (1) , l = 4 × 2 = 8 feet

Area of rectangular deck, A = l× w

=> A = 8× 2 = 16 square feet

So, the required area is 16 square feet.

Answer:

Part A

12 months a year means

Part B

4 weeks in a month means

because in the thousandths place was a 5 and you round up when there is a 5 or above

Part C

We will go with 31 days in a month, but I will also do 30 for you

$74.5 ÷ 30 = $2.48333

But rounded to the nearest penny. . .

How do you find cubic root?? Theres not a specific question, I just need to know.

Answers

Answer and Step-by-step explanation:

Picture this:

There is a base number, and when this number gets multiplied by itself 3 times, we say the number got cubed.

To find the cubic root, we find the number that had to multiply itself 3 times that got the bigger number.

Example:

Let's say we are given the number 27.

If we take the cube root of 27, we get 3.

[tex]\sqrt[3]{27}[/tex] = 3

This is because 3 times itself 3 times is 27.

3 × 3 × 3 = 27

9 × 3 = 27

27 = 27

Another Example:

We are given the number 970299.

If we put this into a calculator and press the button to do this: [tex]\sqrt[3]{x}[/tex], then, in some calculators, it would look like this: [tex]\sqrt[3]{972099}[/tex]

We we click to solve, we get that base number, or the cubed root, to be 99.

That means 99 was multiplied by itself 3 times to get 972099.

Using the property of similar triangles, we found that the value of n is 5.

This is the length of the side RQ.

What are similar triangles?

If two triangles have an equal number of corresponding sides and an equal number of corresponding angles, then they are similar. Similar figures are described as items with the same shape but varying sizes, such as two or more figures. Triangles with the same shape but different sizes are said to be similar triangles. Squares with any side length and all equilateral triangles are examples of related objects. In other words, if two triangles are identical, their respective sides are equal in number and their corresponding angles are congruent.

The given triangles are both right triangles.

So they can be considered similar triangles.

One of the properties of similar triangles is that the ratio of corresponding sides is always equal.

Then we can write for the given triangles,

BA/RQ = AC/QS

2/n = 4/10

n = 2 * 10 / 4 = 5

Therefore using the property of similar triangles, we found that the value of n is 5.

5/8 were non fiction or picture books, so ’the rest‘ of the chapter books is 3/8.

3/8 were chapter books, or 24.

add the amount of picture books and chapter books since they are the fictional texts.
