An equilateral triangle has sides of equal length. Find the dimensions of an equilateral triangle with a perimeter of 45 inches. P=4s

P= 4s

P= 4(45)

P= 180 in.

Explanation: write down the formula first. Then write down P= 4s, but change the "s" to the 45. Then multiply 45 by 4 then you have your answer. If your teacher ask you for an degrees it will be 180°. Which is also the sum of a triangle.
