Answer:
6 cm²
Step-by-step explanation:
Since 3 side lengths are given, I assume that this figure is a triangle. The area of a triangle can be determined by using hero's formula.

⇒ s = Perimeter/2
⇒ a, b, and c = side lenths of triangle
<u>Replacing a, b, and c as the given side lengths:</u>

<u>Determining the perimeter of the triangle:</u>



<u>Determining the half of perimeter:</u>



<u>Replacing the value of "s" in the formula:</u>

<u>Evaluating the area:</u>




You need to multiply 1 and 5 plus 2.
and for 5 2/7 it would be 5 times 7 plus 2.
So...
5 2/7= 37/7
1 2/5= 7/5
$220.87 , (it would be $220.88 if you have to round up though
