Answer 2

28 & 37 cm

Explanation:

Perimeter(P)=9 cm

Let the equal sides(a) be x cm, then third side(b)=(x+9)cm

We have,

P=Sum of all sides

93=a+a+b

or,93=2a+(x+9)

or,93=2x+x+9

or,93-9=3x

or,84/3=x

therefore, x=28

Now,

Length of equal sides=x=28cm

Therefore, The length of each of the two equally long sides is 28 cm

The length of the longer side=(x+9)=28+9=37cm
