Answer:
62.1467 square units (correct to four decimal places)
Step-by-step explanation:
Let's say the triangle is;
A(-7,5)
B(-4,1)
C(0,1)
Let's say also that AB = a , BC = b and AC = c
By measurement BC = 4 units , AB = 5 units (applying Pythagorean theorem) and AC = 8.1 units (correct to one decimal place) also through Pythagorean theorem.
Area of this triangle =
, where p is half the perimeter of the triangle
p =
units
Area =
= 62.1467 square units (correct to four decimal places)
Answer: 200 divided by 4 = 50 so the answer should be 50 weeks.
Step-by-step explanation:
B² - 4ac
= 8² - 4*(-2)*(-9)
= 64 - 72
= -8
