There are 12 such shapes. One can start with two squares, adding squares around the edge and rejecting shapes that have been previously seen. Repeating until you have 5 squares results in 12 distinct shapes.
_____
2 shapes are possible with 3 squares: L, I
5 shapes are possible with 4 squares: L, I, N, T, O
One little tool that you should always remember when you work
with percents is this:
The symbol ' % ' means ' /100 ' .
So ' 32% ' means ' 32/100 ' . There's your fraction.
If you want to simplify the fraction, divide the top and bottom numbers
by their greatest common factor. The greatest common factor of 32
and 100 is 8.
32/100 = 4/25 . There's your simplified fraction.
To find the decimal, you have two choices:
Choice #1:
A fraction always means division. Whenever you see a fraction,
it means "the top number divided by the bottom number".
Take one of the fractions ... 32/100 or 4/25 ... and do the division,
with your pencil or your calculator. The quotient will be the decimal.
Choice #2:
Another little tool that you should always remember
when you work with percents:
To change a decimal into a percent, move the
decimal point two places that way ==> . 0.25 = 25.%
To change a percent into a decimal, move the
decimal point two places this way <== . 32.% = 0.32
There's your decimal.
X=9 because area is length times width (5 times x) so you would divide 45 by 5 and get 9
