step by step explanation:
let the length =8x
breadth = 9x
ATQ
2(8x+9x) = 102
17x = 51
x = 3
length = 24cm

ratio of sides of rectangle = 8:9
So, Let 8x & 9x be the dimensions of rectangle
Given, perimeter of rectangle = 102cm
2(8x + 9x) = 102cm
2*17x = 102cm
34x = 102cm
x = 102/34
x = 3cm
Since, 8x and 9x are dimensions of rectangle
So, dimensions of rectangle are:-
8x = 8*3 = 24cm
and, 9x = 9*3 = 27cm
Hence, length of rectangle = 27cm.
and , it's breadth = 24cm
