The area of an equilateral triangle with sides of length 'a' is given by the formula:
A = (sqrt(3) / 4) * a^2
Substituting a = 17, we get:
A = (sqrt(3) / 4) * 17^2 = 133.257...
Rounding this to the nearest tenth, we get:
A ≈ 133.3 square inches.
Therefore, the area of the piece of art to the nearest tenth is approximately 133.3 square inches.
A = (sqrt(3) / 4) * a^2

Therefore, the area of the piece of art to the nearest tenth is approximately 133.3 square inches.
