Find the area of the triangle.

Ne4ueva [31]

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.

$A = \frac{1}{2}bh$ , where $b$ represents base and $h$ represents height.

So, if we substitute our given measurements with the variables in this formula, we can easily solve this.

$A = \frac{1}{2}(2.8)(7.8)$

Then, using the order of operations, we multiply and ultimately solve this problem.

$\frac{1}{2}*2.8 = 1.4$

$1.4*7.8=10.92$

Thus, our answer is 10.92cm.
