Compute the area of a triangle with sides. 10 x 10 x 16 area = ? square units

48 square units

Step-by-step explanation:

To find the area of this triangle, we may use Hero's formula:

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

where s is the semi - perimeter, a, b, and c are the measure of the sides. 

                                 s = (a + b + c) / 2

                                   = (10 + 10 + 16) / 2

                                   = 18

Substituting this in the equation for area,

                        A = sqrt ((18)(18 - 10)(18 - 10)(18 - 16)) 

                                 A = 48 units²
