The perimeter of a ruler that measures 6 in. by 5656 in. is 11,324 in.
Explanation:
To find the perimeter<span> of a rectangle or square you have to add the lengths of all the four sides.</span>
The answer is 80 because of 16 times 5 that's how you get your answer
hope this helps :)
The formula is d=C/π.
The diameter is 2 times the radius
The formula for the circumference using the radius is 2πr.
in order to do this backwards, we would have to do 16÷2÷π, but we're not looking for the radius.
Therefore, we take out the ÷2 part, which would be 16÷π
16 is the circumference
16÷π=d
d=C÷π
So you do $90 times .40 because 40%=.40 then next you set up your problem
90x.40=36
In total the sales price is $36
