Write a function rule for the area of a triangle with a base 4 in less than twice the height

A = h² - 2h

the area (A) of a triangle is

A = × base × height

let height be h then base = 2h - 4 =2(h - 2)

A = × 2(h - 2) × h

  = h(h- 2) = h² - 2h

81 seats

step-by-step explanation:

if you multiply 0.65 times 125 then you get 81.5 seats. well since you can't have half of a seat you have to round down and get 81 seats in the no children zones. that leave 44 seats outside of the no children zone.
