Guadalupe owns 2 rectangular tracts of land. One is 300 m by 500 m and the other is 250 m by 630 m. The combined area of these 2 tracts is how many square meters?
3,360
307,500
621,500
704,000
2,816,000
矩形的面积等于长宽之积,所以两块地的组合面积为(300)(500) + (250)(630) = 150,000 + 157,500 =307,500.
题目理解:是2个矩形之和不是共同部分面积
