Answer:
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
