Question

find the third side of triangle whose semiperimeter is 30cm, and two sides are 24cm and 10cm.​

Answer 1

Answer:

semi perimeter= perimeter/ 2 = 30cm

let third side be X

so, 10 + 24 + x = perimeter

54 +x = perimeter

Semi perimeter = 30 = (34+x) / 2

60 = 34+x

X = 26 cm

so the third side of triangle is 26 CM
