Question

Two sides of a triangle measure 20cm and 25cm . If the semiperimeter of the triangle is 32cm ,then the length of the third side is _ cm.​

Answer 1

Step-by-step explanation:

a triangle sum of length of the either of the two sides of a triangle is always greater than the third side so third side will be less then sum of the length of two given sides i.e.(6+8=14cm) and also the difference of the length of either of two sides will be less than the third side so, third side will be greater than the difference of these two (8-6=2cm)

so, third side will be greater than 2cm and less than 14cm

Answer 2

Step-by-step explanation:

let the third side be= x

semiperimeter =32 cm

semiperimeter = sum of all sides/2

32=20+25+x/2

32×2=20+25+x

64=45+x

x=64-45
