Work: Calculate the value of equation 1/2*2100*557^2-1/2*(2100-200)*(577-180)^2 .
Question type: Mathematical calculation
Solution:
1/2*2100*557^2-1/2*(2100-200)*(577-180)^2
=1/2*2100*557^2-1/2*1900*(577-180)^2
=1/2*2100*557^2-1/2*1900*397^2
=1/2*2100*310249-1/2*1900*397^2
=1/2*2100*310249-1/2*1900*157609
=0.5*2100*310249-1/2*1900*157609
=1050*310249-1/2*1900*157609
=325761450-1/2*1900*157609
=325761450-0.5*1900*157609
=325761450-950*157609
=325761450-149728550
=176032900
Answer:1/2*2100*557^2-1/2*(2100-200)*(577-180)^2=176032900
