L =

w
a = 12
Length times width = area
L · w = a

w · w = 12

= 12
Divide both sides by

or mulitply both sides by

(either one is fine)

÷

= 12 ÷

or

= 12


= 18
Square root both sides to get rid of the squared on the w

=

w = 4.24
the answer is 3 u only need to remove the - sign
I would go with 12.5
I’m more of an English person but that’s my best guess.
3/24
1/8
1 divided by 8
=12.5
Hope you get it right :)
