Question

If a triangle has side lengths of 14 centimeters and 18 centimeters and the perimeter is 49 centimeters, how long is the third side?

Answer 1

17

Explanation:

First side+second side+third side=perimeter

14+18+third side=49

32+third side=49

Subtract 32

third side=17

P= a+b+c

Perimeter is sum of sides

49= 14+18+x

x= 49 - 32= 17 cm
