To find the height of the tent, we can use the Pythagorean theorem in three dimensions.
Let's label the height of the tent as h.
The slant height of the tent forms a right triangle with the height and one of the edges of the square base.
The length of the edge of the square base is given as 20 m, and the slant height is given as 13.5 m.
Using the Pythagorean theorem, we have:
h^2 + 20^2 = 13.5^2
Simplifying and solving for h, we get:
h^2 + 400 = 182.25
h^2 = 182.25 - 400
h^2 = 217.75
h ≈ √217.75
h ≈ 14.8
Therefore, the height of the tent is approximately 14.8 m.
The correct answer is:
14.8 m

To find the length of the ramp needed to fit diagonally in the cage, we can use the Pythagorean theorem in three dimensions.
Let's label the length of the ramp as r.
The length of the cage is given as 70 cm, the width is given as 35 cm, and the height is given as 50 cm.
To find the diagonal length within the cage, we need to find the diagonal of the rectangular prism. This can be done by finding the diagonal of the base and using it as one side of a right triangle, with the height as the other side.
Using the Pythagorean theorem:
r^2 = 70^2 + 35^2 + 50^2
r^2 = 4900 + 1225 + 2500
r^2 = 8625
r ≈ √8625
r ≈ 92.9
Therefore, the length of the ramp needed to fit diagonally in the cage is approximately 92.9 cm.
The correct answer is:
92.9 cm
