Question

The width of a hall is ¾ of its length. If its perimeter is 56 m, then find length and breadth of the hall.​

Answer 1

Answer:

Length is 16m and Breadth is 12m.

Step-by-step explanation:

Let the length be x.then,

the width is 3x/4.

So,

2(x+3x/4) = 56

2 ( 7x/4) = 56

[If you solve (x+3x/4) you get 7x/4]

2(7x/4) =56

7x/2 = 56

7x = 56×2

7x = 112

x = 112/7

x = 16

So, the length is 16m and breadth is 12m. (¾×16)

That is your answer.
