Question

Perimeter of a rectangular field is 1280 metres the ratio between it's sides is 3 ratio 2 find its length

Answer 1

Answer:

perimeter = 1280 metre

let length be 3x

breadth be 2x

=> perimeter of rectangle = 2(l+b)

=> 1280 = 2(3x+2x)

=> 1280 = 2× 5x

=> 1280 = 10x

so, x = 1280/10

x = 128

length = 3x = 3× 128 = 384 metre
