D.9x+9x+8x+8x=68

Answer 1

Answer 2

length : width = 9:8

so let length = 9x,
width = 8x

ok?

Answer 3

yes

Answer 4

perimeter of rectangle = sum of sides = 2* length + 2* width

Answer 5

l*w?

Answer 6

length = l = 9x
width = w = 8x

perimeter = 2*(9x) + 2*(8x) = 68

Answer 7

or
9x + 9x+ 8x+8x = 68

Answer 8

ohhhhh so it is D??
