3. A quadrilateral with each side length 4 cm

Step-by-step explanation:

We need to understand what is a unique polygon?

It means all regular polygons with the same number of sides are similar.

1.A triangle with angles 30 degrees, 60 degrees, and 90 degrees

It is an right triangle, so the 3 sides are not simillar, so it is wrong

2. A triangle with side lengths 5 cm, 4 cm, and 3 cm

It is a triangle with the 3 sides are not simillar, so it is wrong

3. A quadrilateral with each side length 4 cm

It is an square with the 4 sides are simillar, so it is true

4. A triangle with side lengths 7 cm and 8 cm and a 40-degree angle

It is a triangle with the 3 sides are not simillar, so it is wrong

Hence, we choose 3.

The moats separating people from the animals are 5 m wide for lions and 4 m wide for the elephants. If the lion’s moat is 4 m de

ZanzabumX [31]

Answer:

The elephants' moat should be 3.2 meters deep.

Step-by-step explanation:

Suppose, the depth of the elephants' moat is $x$ meter.

Width of the lions' moat is 5 meter and width of the elephants' moat is 4 meter.

Given that, the lion’s moat is 4 meter deep.

So, according to the ratio of width and depth, the equation will be.......

$\frac{5}{4}=\frac{4}{x}\\ \\ 5x=4*4\\ \\ 5x=16\\ \\ x=\frac{16}{5}=3.2$

Thus, the elephants' moat should be 3.2 meters deep.
