Question

The length of a rectangle is four times its width. The perimeter of the rectangle is at most 130 cm

Which inequality models the relationship between the width and the perimeter of the rectangle?

Answer 1

L = 4w

2L + 2W ≤ 130 cm

I would use the substitution method for this one.

Answer = 2(4w) + 2w ≤ 130 cm
