Answer:

Area: 9cm²

Perimeter: 12 cm

Explanation:

Area is length x width

It's a square so length and width are the same

3 times 3 is 9

And to find the perimeter you just add the side lengths

Squares have 4 sides and the given side length is 3 so 3x4 OR 3+3+3+3 is how you get the perimeter.

Area of a Square

Perimeter of a Square

There are two parts in this question. In first part we have to find area and in second part we have to find perimeter of a Square.

$\\ \\$

$\green{ \text{part \: 1}}$

$\\$

To find Area of a Square :

we know:

$\bigstar \boxed{ \tt{Area \: of \: a \: Square = }{ \tt{side}^{2} }}$

$\\$

So :

$\\$

$\dashrightarrow \sf{Area \: of \: a \: Square = }{ \sf{side}^{2} }$

$\\ \\$

$\dashrightarrow \sf{Area \: of \: a \: Square = }{ \sf{3}^{2} }$

$\\ \\$

$\dashrightarrow \sf{Area \: of \: a \: Square = }{ \sf3 \times 3}$

$\\ \\$

$\dashrightarrow \sf{Area \: of \: a \: Square = }{ \sf9cm {}^{2} }$

$\\ \\$

$\therefore \underline \textsf{ \textbf{Area \: of \: a \: square \: = \red{9 {cm} }}} \red{ \bf^{2}}$

$\\ \\$

$\green{ \text{part \: 2}}$

$\\ \\$

To find perimeter of square :

$\\ \\$

$\bigstar \boxed{ \tt{Perimeter \: of \: a \: Square = }{ \tt4 \times {side}}}$

$\\ \\$

So:

$\\ \\$

$\dashrightarrow \sf{Perimeter \: of \: a \: Square = }{ \sf4 \times side} \\$

$\\ \\$

$\dashrightarrow \sf{Perimeter \: of \: a \: Square = }{ \sf4 \times 3} \\$

$\\ \\$

$\dashrightarrow \sf{Perimeter \: of \: a \: Square = }{ \sf12cm} \\$

$\\ \\$

$\therefore \underline{ \textsf{ \textbf{perimeter \: of \: a \: square \: = \red{12cm}}}}$

Decrease £1280 by 60%

klemol [59]

Hi rainy here !!! so lets see lets set up your problem like this

X/1280 = 60%/100 so lets cross multiply

100 times X =100X

60 times 1280 = 76800

100X=76800 now lets divide each side by 100

100 divided by 100 = 0

76800 divided by 100 = 768

X=768

So now we have to subtract to get the total amount so 1280 minus 768 = 512

512 is your answer :)

Hope I helped if u have any questions on how I did your problem feel free to message me or comment on my page bye !!!

Love ~Rainy~

In Jeremiah class

Irina18 [472]

Answer:

2/5 = 4/10

4/10 = 40%

Explanation:

2/5 is a simplified fraction, and one of the bigger fractions it’s made by 4/10. Do you can use 4/10, but can also use 8/20, 20/50, 40/100, so on. Since we know that any fraction that of ten can be turned into a percentage easily (2/10=20%, 5/10=50%,9/10=%90), then 4/10 is equal to 40%. So 40% of the people in Jeremiah’s class are boys.
