Answer 1

@Michele_Laino

Answer 2

if L is the length and W is the width, then we can write:
\(L=5\cdot W\)

Answer 3

hint:
the perimeter of your rectangle is:
\(2(L+W)=96\)

Answer 4

now I substitute, so I get this:
\(2(5W+W)=96\)
please solve that equation for \(W\)

Answer 5

how?

Answer 6

start with the bracket
...add like terms ...(5W+W)

Answer 7

would that equal 5w?

Answer 8

no

Answer 9

?

Answer 10

ok eg... what W+W=?

Answer 11

W

Answer 12

no 2W

Answer 13

what is:
\(5W+W=...\)

Answer 14

you have to sum: \(5+1\)

Answer 15

6

Answer 16

ok! so we can write: \(5W+W=6W\)

Answer 17

now what is \(2\cdot 6W=...?\)

Answer 18

12w?

Answer 19

correct!

Answer 20

so we get this equation:
\(12W=96\)

Answer 21

ok

Answer 22

If I divide both sides by 12, I get:
\[\frac{{12W}}{{12}} = \frac{{96}}{{12}}\]

Answer 23

so, what is \(96/12=...?\)

Answer 24

so solve 96 divided by 12 right?

Answer 25

right!

Answer 26

8!

Answer 27

correct! you got the right answer

Answer 28

Great thank you
