'B

Answer 1

The area of the triangle is 34.2 square centimeters

How to determine the triangle area?

The sides of the triangle are:

a = 8

b = 9

c = 10

Start by calculating the semi-perimeter using:

s = (a + b + c)/2

This gives

s = (8 + 9 +10)/2

Evaluate

s = 13.5

The area is then calculated using:

$Area = \sqrt{s * (s -a) * (s -b ) * (s - c)}$

So, we have:

$Area = \sqrt{13.5 * (13.5 -8) * (13.5 -9) * (13.5 - 10)}$

Evaluate

Area = 34.2

Hence, the area of the triangle is 34.2 square centimeters
