is the measurement 9.6 cm?

Answer 2

  An equiangular triangle has 3 equivalent sides, and its perimeter is the same as any side times 3. 96 times three is 288, so the perimeter of the square and triangle is 288. Any side length of a square is the same as the perimeter divided by four, since the perimeter is made up of four equal sides. 288 divided by 4 is 72.
