The first and the second statements are correct
i think
Here we are given the three sides of the triangle.
So we have Heron's formula to find its area.
Heron's formula is given by :

where A, B and C are sides of triangle and S is semi perimeter which is given by,

plugging values of A, B and C to find S

S=13.5
Now plugging values of A, B , C and S in Heron's formula

A=26.14 mm²
Answer: Area of triangle is 26.14 mm².
<span>The answer is 500 Because if you $2,000 +$9,000 = 11,000
11,000 - 10,000 - 500 = 500
