Question type: Mathematical calculation
Solution:
4×((50^2+100^2)+(150^2+100^2)+(50^2+200^2)+(150^2+200^2)+(50^2+300^2)+(150^2+300^2)+(50^2+400^2)+(150^2+400^2))
=4×(12500+(150^2+100^2)+(50^2+200^2)+(150^2+200^2)+(50^2+300^2)+(150^2+300^2)+(50^2+400^2)+(150^2+400^2))
=4×(12500+32500+(50^2+200^2)+(150^2+200^2)+(50^2+300^2)+(150^2+300^2)+(50^2+400^2)+(150^2+400^2))
=4×(12500+32500+42500+(150^2+200^2)+(50^2+300^2)+(150^2+300^2)+(50^2+400^2)+(150^2+400^2))
=4×(12500+32500+42500+62500+(50^2+300^2)+(150^2+300^2)+(50^2+400^2)+(150^2+400^2))
=4×(12500+32500+42500+62500+92500+(150^2+300^2)+(50^2+400^2)+(150^2+400^2))
=4×(12500+32500+42500+62500+92500+112500+(50^2+400^2)+(150^2+400^2))
=4×(12500+32500+42500+62500+92500+112500+162500+(150^2+400^2))
=4×(12500+32500+42500+62500+92500+112500+162500+182500)
=4×700000
=2800000
Answer:4×((50^2+100^2)+(150^2+100^2)+(50^2+200^2)+(150^2+200^2)+(50^2+300^2)+(150^2+300^2)+(50^2+400^2)+(150^2+400^2))=2800000
