Answer 1

Answer:

area of traingle a+b+c

1.60cm,153cm,111cm

a=60cm

b=153cm

c=111cm

area of traingle=60+153+111

=324cm

2.5m,7m,8m

a=5m

b=7m

c=8m

area of traingle=5+7+8

=20m

3.50cm,78cm,112cm

a=50cm

b=78cm

c=112cm

area of traingle=50+78+112

=240cm

4.60cm,61cm,11cm

a=60cm

b=61cm

c=11cm

area of traingle=60+61+11

=132cm
