Question

find the area of a triangle whose the two sidea is 8cm and 11cm and its perimeter is 32cm.​

Answer 1

Answer:

8

Step-by-step explanation:

s(semi-perimeter) and a,b and c are sides of a triangle

using Heron's formula,

a=8 cm

b=11 cm

c=32-(8+11)

c=32-19

c=13 cm

s=8+11+13/2=16

2*2*2*

8

Answer 2

Answer:

perimeter means sum of all sides

here we kown the 2 sides I.e 8cm and 11 cm

third side= 32-11+8

32-19

=13 cm
