There is only one basic shape for an equilateral triangle. The area can only vary as the length of the sides vary.
The answer is 32 cm. because the formula for the area of a triangle is 1/2*base*height. Since its an equilateral triangle, it has equal sides. so just substitute it to the given formula. It will be 1/2*8*8 so therefore its 32 :)
In our example, the area of the equilateral triangle is 1/6 of the area of the regular hexagon

The area is 1.2 (1.16463) m2

If the sides are different lengths it ain't equilateral...
In our example, the area of the equilateral triangle is 1/6 of the area of the regular hexagon
225(radical "3")/4
It will be 9 times as large. And that will be true for any plane shape, not just an equilateral triangle.
By definition, an equilateral triangle has all three sides of equal length! So it is impossible for it to have sides of length 10 inches and 7 inches!
