i need the picture to figure it out :|
The formula for the perimeter is \(P =2(\rm length + width)\).
Since the length is \(15\) and the width is \(x\), we have this equation:\[2(15 + x) = 54\]Solve for \(x\).
ok figure it out based on the info parth gave (unless you want me to explain more)
would you like more explanation?
OK, so do you know that the perimeter is the sum of ALL sides?
Notice that opposite sides in a rectangle are equal.|dw:1357571260853:dw|
So the sum of sides will be \(15 + 15 + x + x\). But it is also given that the sum of all sides (perimeter) is \(54\).
So solve the equation \(15 + 15 + x + x = 54\)?
I have to go study for exams for a few min, so let parth finish =3
You have to figure out what x is, right?
OK so you divide 15 right?
I can't get on my study page o_o no don't divide by 15 subtract 15+15 from the perimeter and then divide by 2
that should be your answer
no i think you did it wrong let me try
54-30=? then divide ? by 2 to get answer
o_o no, sorry but very close
how did you get 11?
22 divided by 2
ok then? whatever i wish you good luck on your hw or whatever it is your doing
