Find the area a of polygon abcdefg with the given vertices. a(0,5) , b(2,5) , c(2,3) , d(3,2) , e(1,2) , f(0,3) , g(−4,3)

According to modern science, earth is about 4.5 billion years old and written human history extends back about 10,000 years. suppose the entire history of earth is represented with a 10-meter-long timeline, with the birth of earth on one end and today at the other end.

If 2(a^2+b^2)=(a+b)^2 then, > a+b=0, > ab=0, > a=b, > 2a=b
