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.

  • Side of a Square = 3cm

\\  \\

\star  \blue{\frak{To \: find :}}

\\  \\

  • Area of a Square

  • Perimeter of a Square

\\  \\

\star  \orange{\frak{Solution :}}

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}}

\\

<u>To find Area of a Square </u><u>:</u>

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}}

\\  \\

<u>To find perimeter of square </u><u>:</u>

\\  \\

\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}}}}

1. At the gym on Monday, Larry is told to up his weight on the bench-press by 15% from last week. Last week he was bench-pressin
QveST [7]

Answer:

300 lbs

Step-by-step explanation:

We know that Larry bench pressed 200 lbs last week, and that he is supposed to increase by 15%. We know that any number times one is that same numbers. That means a number that is increaseing has to be greater than 1. So, we have to convert 15% into a decimal. That is 0.15. That plus one is 1.15. Now we just have to multiply 1.15 with 200. We get 300.
