A table top is in the shape of an equilateral triangle. If the perimeter of the
table top is 255 inches, what is the length of one side of the table?
A. 765 inches
B. 258 inches
C. 252 inches
D. 85 inches

The correct answer is D: 85 inches

Step-by-step explanation: The figure specified in the question is an equilateral triangle and one of it's properties is that all three sides have equal measurements.

The perimeter simply is a measurement of the lengths that runs around the entire shape. In other words the perimeter of a triangle is given as

Perimeter = 3L

Where L is the length of one side of the triangle.

If the perimeter of the table top is given as 255 inches, then we can now express it more properly as follows

255 = 3L

Divide both sides of the equation by 3

85 = L

Therefore the length of one side of the table measures 85 inches.
