A given map is enlarged 3 times its original size which is 1;150,000 what will be the new scale? A. 1 : 50,000 B. 1 : 75,000 C. 1 : 100,000 D. 1 : 450,000 Detailed SolutionA is correct; when the map is enlarged the new scale is 1 : 50,000A is correct. when the map is enlarged the representative fraction becomes smaller i.e. 1: 150,000/3 = 1: 50,000 |
