Answer:
10cm < x < 60cm
70cm<p<120cm
Step-by-step explanation:
The third side of a triangle can be no smaller than the difference of the two other sides and no greater than the sum
Let the two sides be a and b, where b is the bigger of the two sides
b-a < x < a+b
35-25 < x < 25+35
10cm < x < 60cm
The perimeter is the sum of the three sides
10+25+35 < p<60+25+35
70<p<120
