This is a carnivorous plant that resembles a common shrub or pine. This plant can be grown up to 1.5m in height. The leaves
of this plant are narrow and triangular. Flowers that sprout out
of this killer plantare beautiful and bright yellow colour.

the answer would be the third option, "no, ariel should have added 9^2 and 12^2 and compared that to 15^2."

this is found through the pythagorean theorem, which is a^2 + b^2 = c^2.

this is the correct way of solving the problem:

9^2 + 12^2 = 15^2

81 + 144 = 225

225 = 225
