Find the area of abc. round your answer to the nearest tenth. b=87, a = 10.1, c = 9.8

a. 44.5

c. 49.4

b. 33.6

d. 77.1

The area of the triangle can be calculated through the equation,

A = sqrt ((s) (s - a) (s - b) (s - c))

where A is area, s is the semiperimeter ((a + b + c) / 2), a, b, and c are the sides given above.

The presented equation above is the Heron's formula.

Substituting the known values,

s = (8.7 + 10.1 + 9.8) / 2

s = 14.3

A = sqrt ((14.3) (14.3 - 8.7) (14.3 - 10.1) (14.3 - 9.8))

A = 38.9 units squared

Thus, the answer to this item is not among the choices.
