HELP!!!!
IMPOSSIBLE!!! Look if you have the area of 24 lets say, so the dimensions can either be 24 & 1 (so the P=(24+1)2=50 ) 12 & 2 (so the P=(12+2)2=28 ) 8 & 3 (so the P=(8+3)2=22 ) 6 & 4 (so the P=(6+4)2=20 ) see what I mean?
See what I mean ? If you have a SQUARE you CAN find the perimeter with just the area.
post the exact question please
I'd take a different approach: I'd choose a letter to represent the width of the rectangle and another letter to represent the length. Knowing the area and the area formula, one can solve for either length or width (as a literal, not a numeric value), and substitute the result into the equation for Perimeter. That will give you the Perimeter in terms of either length or width and is a satisfactory answer.
yeah i agree with @SolomonZelman because did the perimeter and area of circles and some really weird objects but never wat u asked i dont know where u got this question
Perhaps I am just stupid and stink at math , but again, the rectangle can have multiple dimensions. you can't find x. that's what I think :)

i do suck at math got 2 F this semester in math so and i am pretty sure u can not do this
ZRP: Please watch your language. @muppz: good. let width = w = 42/x. Write the formula (the general formula) for the perimeter of a rectangle, Use x for the length and 42/x for the width.
who is zrp ?
ZRP will know if he's still with us.
I didn't see any curse words, so I am kind of confused here.
whatever, I don't want to interrupt the learning process Guys, peace out !
@muppz: Nice work! Just enclose that 42/x within parentheses, or multiply out (2)(42).
thats the length?
wait no
@mathmale is that right? thanks for the help!! You're a great helper
@mathmale is that what you mean by enclose? ^
Nice work! Thank you! Do add that x represents the length of your rectangle. 42/x, enclosed within parentheses, is (42/x). But your formula is fine as it now is.
Sorry for the delay! The 'Net is slow this morning, at least for me. Factoring your expression would indeed make it more elegant. Be sure to label the expression: "P = 2(x + 42/x), where x represents the length of the rectangle."
