Question

The sides of a rectangle are in the ratio 8: 9. If its perimeter is 102 cm, then its length is: ​

Answer 1

step by step explanation:

let the length =8x

breadth = 9x

ATQ

2(8x+9x) = 102

17x = 51

x = 3

length = 24cm

Answer 2

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
