To calculate for the area of the triangle given all its side, use the Heron's formula which is,
A = sqrt ((s)(s - a)(s - b)(s - c))
where A is the area. a, b, and c are the measure of the sides and s the semi - perimeter or half of the perimeter.
With the given above, s = (17 + 18 + 21.4) / 2 = 28.2
Substituting the known dimensions to the Heron's formula,
A = sqrt ((28.2)(28.2 - 17)(28.2 - 18)(28.2 - 21.4)) = 148 units^3
Thus, the area of the triangle is 148 units^3.

Answer:
A. -1
Step-by-step explanation:
2x⁴ - 7x³ + 4x² + 7x - 6
2(1) - 7(-1) + 4(1) + 7(-1) - 6
2 + 7 + 4 - 7 - 6 = 0
6 + 7 - 7 - 6 = 0
2(256) - 7(64) + 4(16) + 7(4) - 6 = 0
512 - 448 + 64 + 28 - 6 = 0
604 - 454 is not equal to 0
2(625) - 7(125) + 4(25) + 7(5) - 6 = 0
1385 - 881 is not equal to 0
