It depends on what the composite figure is, but use the formulas, such as A=1/2bh for the triangle and A=bh, for the square and the rectangle.

Let u = x², then we would have u² + 5u - 6 = 0

From here, we can factor it and get us (u-1)(u+6) = 0

So our solution for u is u = -6 or 1.

Now substitute u back to x².

x² = -6 or 1

x = ±√(-6) or ±√1

Since ±√(-6) is not real number, we ignore it.

Which leave us x = ±√1 = <span>±1

So our real solution is x = -1 or 1.</span>
