Question

the perimeter of a triangle is 62 CM if two side of triangle are 19 cm and 14 cm find the third side

Answer 1

Let the third side be x
Perimeter of the triangle=1st side+ 2nd side + third side

62 = 19+14+x
62=33+x
62-33=x
29=x

so the third side = 29 cm

Answer 2

Perimeter of a triangle = Length1 + Length2 + Length3

.

Find the missing length:

Given that the perimeter is 62cm and the 2 sides are 19 cm and 14 cm

Length3 = Perimeter - Length1 - Length 2

Length3 = 62 - 19 - 14

Length3 = 29

.

Answer: The third length is 29 cm
