Question

The length and breadth of a room are in t]
ratio 7: 6. Find the length if the breadth
12 m.​

Answer 1

☆ Solution ☆

Given :-

• The length and breadth of a room are in the ratio 7: 6.
• The breadth of room is 12 m

To Find :-

• The length of room

Step-by-Step-Explaination :-

Let,

• The length of room be 7x

• The breadth of room be 6x

According to the condition,

7x + 6x = 7x + 12

7x - 7x + 6x = 12

6x = 12

x = 12/6

x = 2

Hence,

The value of x = 2

Thus,

The length of room = 7x = 7 × 2 = 14 m

The breadth of room = 6x = 6 × 2 = 12 m

Hence,

The length of room = 14 m

Answer 2

given that

length : breadth = 7:6

let's assume that

length : breadth = 7x:6x

6x = 12

x = 2

7x = length

7(2) = 14

length = 14m
