The length and breadth of the room are in the ratio 7 ratio 6 find the length of the breadth is 12 metre.
Answers
It is given that,
The length and the breadth of the room is in a ratio 7:6.
Let, the common multiple of the ratio be, 'n'.
Hence we get,
Length = (n×7)
= 7n
Breadth = (n×6)
= 6n
The length of the breadth of the room is 12 m.
∴ According to the problem,
6n = 12
⇒ n = 12/6
⇒ n = 2m.
∴ The length of the room is = (2×7) m
= 14 m.
∴ The perimeter of the room is = 2(length+breadth)
= 2×(14+12) m
= 2×26 m
= 52 m
∴ The perimeter ofthe room is 52 m.
∴ The area of the room is =(length×breadth)
=(14×12) m²
= 168 m².
∴ The area of the room is 168 m².
Answer:
14m
Step-by-step explanation:
Ratio of length to breadth = 7:6
Breath = 12m
Let the lenght be 7x and lenght be 6x
6x = 12/6= 2
lenght=7x
7x2 = 14m
Threrefore, The lenght is 14 m
