The diagram above shows how an equilateral triangle can be cut into four pieces and rearranged to form a square.

If the length of the square is 1327, find the length of the triangle, correct to the nearest whole number.

Areas of triangle and square are equal!

 

If the side length of the square is 1327 units, then the area is A =1327².

 

Side of the triangle is:             s² = A / (√3/4)     smiley
