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?
250.3 in.
204.4 in.
125.1 in.
102.2 in.
The formula to find the area of an equilateral triangle is:
Area = (√3 / 4) x side length^2
Plugging in the given values, we get:
Area = (√3 / 4) x 17^2
Area = (√3 / 4) x 289
Area = 125.436...
Rounded to the nearest tenth, the area of the piece of art is 125.1 in.
Therefore, the answer is option C) 125.1 in.
or ...
area = (1/2)(side1)(side2)sin(angle between them)
= (1/2)(17)(17)sin 60° = 125.14 square inches
The bot got the units wrong!!
