Answer:
10.92cm
Step-by-step explanation:
We can solve this problem by taking the formula to the area of a triangle and substituting our given numbers with the variables in it.
[tex]A = \frac{1}{2}bh[/tex], where [tex]b[/tex] represents base and [tex]h[/tex] represents height.
So, if we substitute our given measurements with the variables in this formula, we can easily solve this.
[tex]A = \frac{1}{2}(2.8)(7.8)[/tex]
Then, using the order of operations, we multiply and ultimately solve this problem.
[tex]\frac{1}{2}*2.8 = 1.4[/tex]
[tex]1.4*7.8=10.92[/tex]
Thus, our answer is 10.92cm.
