6 0

The answer for the question shown above is the las option, which is: <span>D. 2:3 and 4:9.
The explanation is shown below:
1. You have that</span><span> widths of the two similar rectangles are 10 cm and 15 cm. Therefore:
</span> ratio=10:15
ratio=2:3
2- So, the ratio of the perimeter is:
ratio of the perimeter= 2:3
3- The ratio of the areas is:
ratio of the areas=2²:3²
ratio of the areas=4:9

By the Triangle Inequality Theorem which set of side lengths could create a triangle? A) 4, 8, 2 B) 5, 9, 6 C) 6, 8, 16 D) 10, 4

Mazyrski [523]

The answer is B. For a triangle to be possible, no side can be longer than the sum of the lengths of the other two sides. For triangle A, 8 is longer than 4+2, so it is not possible. For triangle B, no side is greater than the sum of the other sides, so it is possible. For triangle C, 16 is greater than 6+8, so it is not possible. For triangle D, 10 is greater than 4+3, so it is not possible.
