Question

two sides of a triangle are 12cm and 14cm.the perimeter of triangle is 36cm.what is its third side?​

Answer 1

Answer:

10 cm

Step-by-step explanation:

perimeter = sum of all side of triangle

let third side = x cm

given perimeter = 36

so

36 = 12+14+x

x = 36-26

x = 10

third side is equal to = 10 cm

Answer 2

Answer:

10

Step-by-step explanation:

Perimeter= 36

A= 12

B= 14

C=?

Formula=

Perimeter = a+b+c

Perimeter - (a+b) = c

36 - (12+14) = c

36 - 26 = c

10 = c

Therefore c = 10
