The lengths of the sides are 24cm, 27cm and 30cm.

Step-by-step explanation:

The ratio of lengths is 8:9:10

Perimeter = 81 cm

Let x be the length of side.

Therefore,

The length of sides is 8x, 9x and 10x.

Perimeter is the sum of 3 sides, therefore,

$8x+9x+10x=81\\27x=81$

Dividing both sides by 27;

$\frac{27x}{27}=\frac{81}{27}\\x=3$

Therefore, the lengths of sides are $8(3), 9(3)\ and\ 10(3)$

The lengths of the sides are 24cm, 27cm and 30cm.
