Okay so let’s calculate the area of the rectangle at the top first. A = length(width) A = (210)(310) A = 65,100 miles Now, solve for the triangle at the bottom. First we need to get the height, so.. 500 miles - 210 miles = 290 miles Now we can use the triangle formula A = base(height)/2 A = 310(290)/2 A = 44,950 miles Now add our two remaining areas. 44,950 miles + 65,100 miles = 110,050 miles Therefore, the first option is correct.
