Jared is creating a flower garden in the shape of a triangle. which could be the dimensions of the garden in feet

A - 2 by 3 by 5

B - 3 by 7 by 9

C - 4 by 5 by 9.5

D - 5 by 6 by 12

B - 3 by 7 by 9 is the only right answer.

Step-by-step explanation:

What is a triangle?

A triangle is a polygon with three edges and three vertices. It is one of the basic shapes in geometry. A triangle with vertices A, B, and C is denoted.

Basic rule:

A triangle must be tri-sided, means it must have three sides which is only possible if the sum of the smaller two sides is greater than the third side. Otherwise, a triangle is not physically possible.

A - 2+3 = 5 hence not a triangle.

B - 3+7 > 9 hence a triangle.

C - 4+5 < 9.5 hence not a triangle.

D - 5+6 < 12 hence not a triangle.
