#l = 5x
#b = 3x
#perimeter = 2 ( l + b )
#1016 = 2 ( 5x + 3x )
#1016 / 2 = 8x
#508 / 8 = x
#63.5 = x
#l = 5 * 63.5 = 317.5
#b = 3 * 63.5 = 190.5
#b = 3x
#perimeter = 2 ( l + b )
#1016 = 2 ( 5x + 3x )
#1016 / 2 = 8x
#508 / 8 = x
#63.5 = x
#l = 5 * 63.5 = 317.5
#b = 3 * 63.5 = 190.5

Given that
Length and breadth are in ratio that is 5:3
Let length be 5x
Breadth= 3x
Perimeter= 1016 sq cm
Perimeter=2(l+b)
1016=2(5x+3x)
1016=16x
1016/16=x
63.5=x
There fore
Length =5x=317.5
Breadth=3x=190.5
