Question

The ratio of length and breadth of a rectangular park is 5:3. If it's length is 320 m, then the perimeter of the park is what

Answer 1

5x=320

x=64

so 3x=198

2(320+198)

1036

so perimeter is 1036m

Answer 2

Answer:

length = 5x = 320

x = 320/5= 64

breadth = 3x = 3*64= 192

perimeter = 2(l+b)

= 2(320+192)

= 2(512) = 1024
