Expert Answer
We see that the side of the square = 8 cm
So the diagonal of the square = cm
Since both are equilateral triangles, so they are equiangular, each of their angles is .
So the two triangles are similar.
Hence the ratio of their areas = ratio of squares of their corresponding sides.
Let A be the area of the equilateral triangle based on the side 8 cm.
Let A' be the area of the equilateral triangle based on the diagonal cm.
