Answer:

For the 1st one: 63

For the second one: 99

Step-by-step explanation:

This is because to find the perimeter, you have to do length+length+width+width=area

So you do 77+77+x+x=280, this should get you x=63

For the second one, to find area you do length×width=area

So you do 59×x=5841 and should get 99.

What are the possible side lengths of a triangle
alina1380 [7]
1. Consider a triangle with sides a, b and c.

2. a, b and c can be sides of a triangle only if each of these conditions hold:

         i)  a+b>c
         ii) b+c>a
and   iii)a+c>b

3. So the only condition for 3 numbers to be the side lengths of a triangle is that the sum of any 2 of them must be larger than the third number

4. This is called the "triangle inequality".
