A piece of art is in the shape of an equilateral triangle with sides of 17 in. What is the area of the piece of art to the nearest tenth?
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.
