If the perimeter of the smaller triangle is 9 cm, what is the perimeter of the larger triangle?

more than 9 cm.

find the perimeter and the area of a rectangle whose vertices have the coordinates [3,2],[-4,3],[3,-3].

10cm

To find the perimeter of the larger triangle, we need to know the relationship between the smaller and larger triangles. Specifically, we need to know if they are similar triangles.

Similar triangles have corresponding angles that are equal and corresponding sides that are in proportion.

If the smaller and larger triangles are similar, then their corresponding sides will be in the same ratio, meaning the ratio of any pair of corresponding sides will be the same.

So, if the ratio of the corresponding sides of the smaller and larger triangles is known, we can use it to find the perimeter of the larger triangle.

However, without knowing more information about the relationship between the triangles, we cannot determine the perimeter of the larger triangle.
