Question

The length of a rectangular field is thrice of it's breadth. If the perimeter of the field is 300m. then find the length and breadth of the field.​

Answer 1

Given,

• The length of a rectangular field is thrice of it's breadth.
• The perimeter of the field is 300m.

To find,

• The length of the field.
• The breadth of the field.

Solution,

      Let the breadth be x m.

      So, length = 3x m.

      According to condition,

      2(x+3x) = 300

      or, 2×4x = 300

      or, 8x = 300

      or, x = 300/8

      or, x = 37.5

So,

• Breadth = x m = 37.5 m.
• Length = 3x m = (3×37.5) m = 112.5 m.

Hence,

• The length of the field is 112.5 m.
• The breadth of the field is 37.5 m.

Answer 2

Answer:

Breath= x

Length =3x

perimeter = 2(length + breath )

perimeter = 2( x + 3x ) =300

2(4x) = 300

8x= 300

x= 300/8

x= 37.5

length = 112.5

breath = 37.5
