Question

Find the area of a triangle, two sides of which are 9 cm and 23 cm and the perimeter is 50 cm.

Answer 1

Step-by-step explanation:

let,

a=9cm

b=23cm

perimeter=50 cm

a+b+c=50 ( sum of all sides of a triangle= perimeter)

=> 9+23+c=50

=> 32+c= 50

=> c= 50-32

therefore, c=18cm

Answer 2

Answer:

given -

a = 9cm

b = 23cm

perimeter = 50 cm

a + b + c = 50

= 9 + 23 + c = 50

= 32 + c = 50

c = 50 - 32

   = 18cm
