Question

Pablo folds a straw into a triangle with side lengths of 4x2 – 3 inches, 4x2 – 2 inches, and 4x2 – 1 inches. The perimeter of the triangle is 12x2 – 6 inches. If x = 1.5, what was the length of the straw before it was folded?

Answer 1

side 1 : 4x² - 3 inches
side 2 : 4x² - 2 inches
side 3 : 4x² - 1 inches

perimeter = 12x² - 6 inches

x = 1.5

12(1.5²) = 12(2.25) = 27 inches

I think the length of the straw before it was folded was 27 inches. - 6 inches is the fold of the straw.
