Answer:

Step-by-step explanation:

The Perimeter of a triangle = 62.5 cm

First side (a) = 18cm

Second side (b) = 21cm

Third side (c) = ?

Perimeter of Triangle = a + b + c = 62.5cm

= 18 + 21 + c = 62.5cm

= 39 + c = 62.5cm

= c = 62.5 - 39 = 23.5cm

Therefore length of the third side is 23.5cm
