Answer :
Given :-
1st side = 12cm
2nd side = 10cm
3rd side = ?
Perimeter = 38cm
Equation that will be formed :-
✡️Take the third side as x
Perimeter = 1st side + 2nd side + 3rd side
=> 38 = 12 + 10 + x
Solving equation :-
=> 38 = 12 + 10 + x
=> 38 = 22 + x
=> 38 - 22 = x
=> 16 = x
Therefore , The 3rd side(x) is 16cm
