Answer:

  5.3

Step-by-step explanation:

The formula for the area of a triangle is ...

  A = 1/2bh . . . . where b is the base length and h is the height.

The figure gives an area and shows b=h, so we have ...

  14 ft² = 1/2(h)(h)

  28 ft² = h² . . . . . . . . . multiply by 2

  h = √28 ft ≈ 5.3 ft . . . . . take the square root
