twelve feet

Answer 1

i need the picture to figure it out :|

Answer 2

The formula for the perimeter is \(P =2(\rm length + width)\).

Answer 3

Since the length is \(15\) and the width is \(x\), we have this equation:\[2(15 + x) = 54\]Solve for \(x\).

Answer 4

ok figure it out based on the info parth gave (unless you want me to explain more)

Answer 5

would you like more explanation?

Answer 6

Yes, please.

Answer 7

OK, so do you know that the perimeter is the sum of ALL sides?

Answer 8

Notice that opposite sides in a rectangle are equal.

Answer 9

So the sum of sides will be \(15 + 15 + x + x\). But it is also given that the sum of all sides (perimeter) is \(54\).

Answer 10

Ok.

Answer 11

So solve the equation \(15 + 15 + x + x = 54\)?

Answer 12

I have to go study for exams for a few min, so let parth finish =3

Answer 13

You have to figure out what x is, right?

Answer 14

Yes! =)

Answer 15

OK so you divide 15 right?
