Question

find the area of a triangle 2 of its sides are 8cm and 11cm and the perimeter is 32 cm.


please answer correctly!!​

Answer 1

Answer:

a=8

b=11

c=32-(8+11)

=13

s= 16

A=8root 30 cm^2

Answer 2

Answer:

Step-by-step explanation: by heron's formula:

area= root of  [s (s-a) (s-b) (s-c) ]

where s= (a+b+c)/ 2

and a,b,c are sides of triangle.

a=8

b=11

perimeter=32=a+b+c

solving c=15

s=16

solving it answer is    8 (root 10)
