triangle 8= 29cm,16cm,21cm
triangle 9= 15cm,26cm,21cm
triangle 10= 26cm,9cm,29cm
triangle 11= 13cm,15cm,9cm
triangle 12= 25cm,31cm,7cm
triangle 13= 9cm,7cm,13cm
triangle 14= 25cm,19cm,15cm

Answer 1

Answer:

the sides of three triangles are 18 cm,15cm ,22cm

=a+b+c/2

=18+15+22/23=55/2=27.5

using the formulae of heron
