Question

2. If the ratio of Length and breadth of a rectangular field is 15: 4. If the perimeter of the field 1520 m. Find
length and breadth of field.

​

Answer 1

Answer:

lenght=600m

breadth=160m

Step-by-step explanation:

lenght/breadth = 15/4

then let,

lenght =15x

breadth = 4x

perimeter = 2(lenght+breadth)

=2(15x+4x) = 1520

= 38x =1520

=> x = 40

then ,

lenght = 600m

breadth = 160m

Answer 2

Step-by-step explanation:

let length= 15x

let breadth=4x

perimeter of the rectangular Field=1520

2(length+breadth) =1520

2(15x+4x)=1520

19x=1520÷2

19x=760

x=760/19or 760÷19

length=15x=15×760/19= 11400/19=600

breadth =4x=4×760/19=3040/19= 160
