Hi Stevie, let x represent the height of the triangle. Then the base of triangle will be 2x.

Equation:

a(rea) = 1/2 * b(ase) * h(eight)

Substitute:

25 = 1/2 * 2x * x

25 = x

^{2}x = ±5

We can discard the negative response since a triangle cannot have a negative length leg.

The height of the triangle is 5 units.

The base of the triangle is 2 * 5, or 10 units.
