The area of a triangle is given by half the multiplication of base and height. Since you want the answer is squared centimeters, let's convert base and height in centimeters first:
[tex] b = 4.3 m = 430 cm, \qquad h = 2.6m = 260 cm [/tex]
Now we can do the computation:
[tex] A = \dfrac{430cm \cdot 260cm}{2} = 55900 cm^2 [/tex]
