40. GEOMETRY The area of a triangle can be found using Heron's Formula, A = (square root)s(s – a)(s – b)(s – c)
where a, b, and c are the lengths of the three sides
of the triangle, and s =
the triangle at the right.
a + b + C /2 Find the area of the triangle at the right

Alake near the arctic circle is covered by a 222-meter-thick sheet of ice during the cold winter months. when spring arrives, the warm air gradually melts the ice, causing its thickness to decrease at a constant rate. after 333 weeks, the sheet is only 1.251.251, point, 25 meters thick. let s(t)s(t)s, left parenthesis, t, right parenthesis denote the ice sheet's thickness sss (measured in meters) as a function of time ttt (measured in weeks).
