Ответ:
Similar polygons will have proportional side lengths. So, let's check each of these using proportions and cross-multiplying.
Proportion: left rectangle length / left rectangle width = right rectangle length / right rectangle width
Top Left Rectangles: Proportional
6.4 / 5.6 = 1.6 / 1.4
8.96 = 8.96
Top Right Rectangles: Not Proportional
10.2 / 6.2 = 5.2 / 1.2
32.24 does not equal 12.24
Bottom Left Rectangles: Proportional
39 / 27 = 13 / 9
351 = 351
Bottom Right Rectangles: Not Proportional
64 / 36 = 8 / 6
288 does not equal 384
Hope this helps!! :)
