Let the breadth of the rectangular field be x so, the length will be 4x area of rectangle = length*breadth ⇒ 30976 = x*4x ⇒30976 = 4x² ⇒30976/4 = x² ⇒7744 = x² ⇒88 = x so length will be = 4x = 4*88 = 352 cm perimeter of rectangle = 2(l+b)cm ⇒ 2 (88+352)cm ⇒2*440 cm ⇒880 cm i hope this will help you

let the - length breadth be x length - 4x area of rectangle - 30976 cm² formula for the area of rectangle - length*breadth x*4x = 30976 x² = 30976 / 4 x² = 7744 x = 88 length is 4x - 4*88 = 352 ∵length - 352 ∵ breadth - 88 perimeter - formula - 2(length + breadth) 2(88+352) 2(440) 880 cm ∵ perimeter is 880cm
