Question

Find the area of a triangle whose sides are 91 cm,96 cm,and 105 cm in length

Answer 1

Answer:

4057.28 sq.cm

Step-by-step explanation:

apply the Heron’s formula to find the area of Scalene triangle

A=sqrt(S(S−a)(S−b)(S−c)) sq.units

S=(a+b+c)/2 , a,b and c are sides of the triangle

S=(91+96+105)/2 =146 cm

A=sqrt(146x(146-91)x(146-96)x(146-105))

A=sqrt(16,461,500)

A=4057.28 sq.cm
