Question

The perimeter of a rectangle is 68 ft. Find the dimensions of the rectangle if the ratio of the length to the width is 9 : 8. Which of the following would be the best equation to use to solve this problem?

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

Answer 1

i would say d

Answer 2

A) 2width + 2length = 68
B) 9w = 8L OR 9W -8L = 0

Multiplying "A" by 4
A) 8W +8L = 272
B) 9W -8L = 0

17W = 272
W = 16
L = 18

Are those equations typed correctly?
'x' is the only unknown in all the equations
