Answer 2

Step-by-step explanation:

first side=51cm

second side=52cm

third side =53cm

area of a triangle =root s(s-a)(s-b)(s-c)

here s is semi perimeter=perimeter÷2

perimeter =sum of all side

=51 +52 +53

=156cm

semi perimiter=156÷2

=78

root78(78-51)(78-52)(78-53)

root 78(27)(26)(25)

root1368900

1170cm^2
