​

Answer 1

47.25 is the answer of question

Answer 2

Answer:

$\:$

Step-by-step explanation:

First to do:-

Let ratio be x= 7x and 3x

Mention the formula:-

Perimeter of rectangle = 2 (l+b)

let's solve:-

30m = 2 (7x+3x)

30m/2 = (10x)

15m = 10x

15m/10 = x

1.5m = x

Hence, 7x = 7x1.5m= 10.5m

3x = 3x1.5m = 4.5m

Required answer:- 4.5m
