Question

the perimeter of a triangle is 64 cm two of its side measures 15 cm and 24 cm respectively find the lenth of third side​

Answer 1

Answer:

Perimeter of the triangle = 64 cm

First side = 15 cm

Second side = 24 cm

therefore, third side = 64 - (15+24)

                                = 64 - 39

                                    = 25 cm

Step-by-step explanation:

Answer 2

Answer:

25cm

Step-by-step explanation:

Let the 3rd side be x

Therefore, 15 + 24 + x = 64

=> 39 + x = 64

=> x = 64 - 39 = 25

Therefore, the 3rd side of the triangle is 25cmc

Verification

(15+24+25) cm = 64 (verified)
