The perimeter of a rectangle is 20.2 CM and it's area is 24.4 cm squared what is its length and width
erma4kov [3.2K]

Answer:

Length of Rectangle = 4 cm    And

Width of Rectangle = 1.9 cm      

Step-by-step explanation:

Given as :

The perimeter of rectangle = 20.2 cm

The area of rectangle is 24.4 cm

Let the length be L

And width be w

Now Area of rectangle = Length × width  

Or,  24.4 = L × W

And Perimeter = 2 (Length + Width ) = 2 (L + W )

Or,   20.2         = 2(L + W )

Or , L + W = 10.1 cm                   ............ 1

Now, (L - W )²  = (L + W)² -4 LW

Or,   (L - W )²  = ( 10.1)² -4 (24.4)

I.e    (L - W )² = 4.41

Or , L - W = 2.1 cm                    .............. 2

SO , From 1 and 2

( L + W) + (L - W) = 10.1 cm - 2.1 cm

Or, 2L = 8

∴  Length = 4 cm

Again , Width = 4 cm - 2.1 cm = 1.9 cm

Hence   Length of Rectangle = 4 cm    And

             Width of Rectangle = 1.9 cm       Answer

in the function y= -1/2(x-1)^2+3, what effect does the negative sign have on the graph, as compared to the graph of y=x^2?
Karo-lina-s [1.5K]

The negative sign will have an effect in terms of which way the graph opens up. Since the function starts off negatively the graph will open down, like an upside down U. Rather if the function started off positive I.e Y=x^2 the graph will open upwards like a upright U.

Ronch [10]

Step-by-step Explanation:

First find out what is the price after 30% off.

250 · 0.3 = 75

250 - 75 = 175

Then find the tax and add it on. Remember to calculate the tax AFTER  the discount.

175 · 0.06 = 10.50

175 + 10.50 = 185.50

Korolek [52]

<em>Answer</em>

Denmark has the greatest population density

Ghana has the least population density

<em>Step-by-step explanation</em>

To find the population density we have to divide the population of each country by its area, as follows:

\begin{gathered} \text{ Population density of Indonesia }=\frac{203,479,000}{1,904,569}\approx106.8\text{ }\frac{people}{sq\text{ }km} \\ \text{Populat}\imaginaryI\text{on dens}\imaginaryI\text{ty of Denmark}=\frac{5,248,000}{42,077}\approx124.7\text{ }\frac{people}{sq\text{ k}m} \\ \text{Populat}\mathrm{i}\text{on dens}\mathrm{i}\text{ty of Ghana}=\frac{18,339,000}{237,533}\approx77.2\text{ }\frac{people}{sq\text{ k}m} \end{gathered}
