A wire is first bent into the shape of a triangle. Each side of the triangle is 12cm long. Then the wire is unbent and reshaped into a square. What is the length of a side of the square?
First find the area of the wire. The wire is 36 square root of 3 or approximately 62.35 cm. Then divide that by 4. The length of a side is 9 square root of 3 or approximately 15.588 cm
