Question

The length and breadth of rectangular hall are in the ratio of 6:5 . If its perimeter is 66 m , find its length and breadth

​

Answer 1

Step-by-step explanation:

Let the length be 6x and breadth be 5x

By the problem, 2(6x+5x)=66m

or, 2×11x=66m

or, 22x=66m

or,x=3m

So, the length will be 6 × 3m = 18m and the breadth will be 5×3m = 15m

Answer 2

Answer:

Let us consider the the real value of length and breadth as 'x'

Step-by-step explanation:

perimeter of rectangular hall = 2(l+b)

2(6x+5x)=66

2(11x)=66

22x=66

X=3

6(3)=18cm=length

5(3)=15cm=breadth
