Answer 2

Answer:

The sides of a triangle are 7 cm, 9 cm and 14 cm. Its area is 

Correct option is

A

125 cm2

Area of triangle = S(S−a)(S−b)(S−c)

S=2a+b+c

Given a=7 cm

b=9 cm

c=14 cm

S=27+9+14

=230

S=15cm

∴ Area of triangle = S(S−a)(S−b)(S−c)

=15(15−7)(15−9)(15−14)

=15.8.6.1

=720

=3×144

=12×12×5

=125cm2

∴ Area of triangle = 12.5 cm2

So, the answer is A. 12.5 cm2
