Question

If the perimeter of the square at the right is 72 units, what are the values of x and y? (Will attach picture.)

Answer 1

i did 3y + 2x = 36 and 4x + 6y = 72 to try to do eliminationt but.... that doesn't make any sense...

Answer 2

what do you know about the sides of a square?

Answer 3

they equal 72

Answer 4

but how do the sides of a square relate to each other?

Answer 5

and i mean any square not just this one

Answer 6

oops i few the picture wrong.... it's supposed to be 3y not 3x...

Answer 7

yea I figured from the equations that was supposed to be a y

Answer 8

the sides of the square equal each other?

Answer 9

yes

Answer 10

so if you relate that to the square in your problem you can safely say that 2x = 3y

Answer 11

so 2x = 3y and 8x= 72?

Answer 12

yes

Answer 13

and x = 9 so 2x is 18 and 3y is 27?

Answer 14

3y = 2x so 3y should equal 2 * 9

Answer 15

hmm but.... myeh so y = 6?

Answer 16

yes good work

Answer 17

hehe thanks
