D. 8-cm square
Step-by-step explanation:
The smaller square shown on the figure has an area of 15×15 = 225. The sum of the two smaller square areas must equal the larger square area, so the smallest square must have an area of ...
289 -225 = 64
Its side dimensions will be √64 = 8 cm.
The diagram is correctly completed by the 8 cm square.
21:18, 42:36, 73:54.
Basically numbers that can be multiplied from the original ratios. Like 7:3, 21:18. 7 is mulitplied 3 times to get 21 and 18 is mulitiplied by 3 7 times to get it. Hope that helps.
