Question

The length and breadth of a room are in ratios 7:6. If the breadth is 9m, then length is _m

Answer 1

Given

✭ Length and breadth of a room are of the ratio 7:6

✭ Breadth = 9 m

To Find

◈ The length of the room?

Solution

Concept

So here we actually will assume that the length and breadth as 7x & 6x so then as it is given that breadth is equal to 9 m then we shall equate them both to find the value of x.So after it we shall substitute the value of x to find the length

━━━━━━━━━━━

Let

☆ Length = 7x

☆ Breadth = 6x

☯ As per the Question

➝ 6x = 9

➝ x = 9/6

➝ x = 3/2

➝ x = 1.5

So now that we know the value of x we shall substitute this in the formula of length

➳ Length = 7x

➳ Length = 7 × 1.5

➳ Length = 10.5 m

∴ Length of the room will be " 10.5 m "

━━━━━━━━━━━━━━━━

Answer 2

Answer:

21

Step-by-step explanation:

let the length be 7x and breadth be 6x

ACCORDING TO THE QUESTION

7x + 6x = 7x + 9

7x + 6x - 7x = 9

7x and -7x will be crossed

6x = 9

x = 9/6

x = 1.5

Length = 7x

= 7 * 1.5

= 10.5

Hope its helpfull
