Correct QUESTION:-

  • Perimeter of a rectangular field is 1280 m. The ratio between its side is 3:2. FIND its length.

⠀

Given:-

  • Perimeter of a rectangular field is 1280 m.
  • The ratio between its side is 3:2.

⠀

To find:-

  • Find its length.

⠀

Solution:-

Let,

  • the length be 3x.
  • the breadth be 2x.

⠀

→ Perimeter = 2(length + breadth)

→ 2(l + b) = 1280

→ 2(3x + 2x) = 1280

→ 2(5x) = 1280

→ 5x = 1280/2

→ 5x = 640

→ X = 640/5

→ x = 128

Therefore,

  • Length = 3x = 3× 128 = 384 m
  • Breadth = 2x = 2×128 = 256 m
