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.

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:

$\\ \\$

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

$\\ \\$

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

$\\ \\$

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

$\\ \\$

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

What strategy can be used to solve 8 x 25 x 23

wariber [46]

The best way to multiply complicated problems mentally* is to break them into chunks.

Start with 20 times 8 to get 160, and then 8 times 5 to get 40. Add these together to get 200. 200 times 3 is 600, and 20 times 200 is 4000. Add these together to get your final answer, 4600.

In other words 8 x 20 + 8 x 5 = 200 200 x 3 + 200 x 20 = 4600

*I assumed you meant mentally, because otherwise you'd just multiply longhand, multiplying two of the three numbers and then multiplying their product with the third.

Solve for x. 2x + 5 = x - 8

Gemiola [76]

2x+5=x-8
-x on both sides
x+5=8
-5 on both sides
x=-13
