okay so the first step in finding the answer is to see what the formula is to determine the area of a rectangle.
do you know the formula?
okay so the formula is A = L * W
where the L stands for length
and the W stands for Width
so based on the picture can you determine what the length and width are?
where are you having issues with that?
yes that is correct!
don't second guess yourself
so the length is 2 2/3 and the width is 3/4
now the easiest way to solve this problem is to convert the fractions into decimals
are you allowed to use a calculator?
okay so then lets try to convert these fractions into whole numbers
do you know how to convert fractions into whole numbers?
okay so worries
so do that we would have to Divide the numerator by the denominator, only if the numerator is a multiple of the denominator.
so for the width, is 4 a multiple of 3?
no it is not
so out only method would be to convert it into a decimal
do you know what 3/4 is in decimal form?
it is .75 because if you have 4 quarters which equal .25 then 3 quarters equal 75
now we move onto the length 2 2/3
now we already have 2 as a whole number and we can convert 2/3 into a decimal
so we basically do 3 /2
3 does not go into 2 so we put a decimal so it is 0.
then we see how many times 3 goes into 20
how many times does 3 go into 20?
no it is 6 times, because 3*6 = 18
so now we have 0.6
and we bring down the reminder
so we have 3/20
and we have a repeating decimal so our answer is
2/3 = 0.66666
so if we add the whole number we have 2.6666
so now we can plug that into the equation
A = L * W
A = 0.75 * 2.6666
Are you with me so far?
do you have any questions?
great now we just multiple 2.66 * 0.75
can you do that and tell me what you get?
AWESOME!
Now we can round that to the closest number
what is that?
do you know what 1.995 to the closest whole is?
GREAT!
so your answer is
0.75 * 2.66 = 2
ANY QUESTIONS?
Do you know the formula for the perimeter of a rectangle?
P = 2( L + W)
so from the information that we already have, can you plug in the numbers for me?
close, try again
and this time for it in fromula form
use the formula that I have provided for you
so can you tell me the formula for the perimeter of a rectangle?
great
so P is the value we are looking for and the rest is the formula
can you now try to plug in the numbers into the formula
starting with P =
GREAT!
now don't forget the parentheses
so try one last time
Awesome!
So now according to the laws of PEMDAS what would be our first step into solving this equation?
where did you get 3.41 from?
yes
so 2.66 + 0.75 = 3.41
now we have P = 2 (3.41)
so we now multiple 3.41 * 2
what do you get when you do that?
great job!
so now we know P = 6.82
and those are your two answers
A = 2
P = 6.82
do you have any questions?
