Question

The length and breadth of a rectangular are in the ratio 5:3 if its perimeter is 128m find the diamantion of the field​

Answer 1

Answer:

If the ratio of the length and breadth of the field is 5:3 it means that a rectangle with sides 5 and 3 is similar (in the technical sense) to the actual field. The perimeter of the similar rectangle will be proportionate to the perimeter of the field (128 meters in this case). The perimeter of the similar rectangle is 16 (2*5+2*3). 128/16 = 8. That us The scaling factor from the similar recrangle to the field is 8.

Step-by-step explanation:

Answer 2

Answer: length=40m and breadth=24m

Step-by-step explanation: let length be 5x and breadth be 3x

perimeter = 128m

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

so, 2(5x+3x)=128

     2(8x)=128

      16x=128

         x = 128÷16

         x = 8

so length = 5x = 5×8 = 40m

and breadth= 3x= 3×8= 24m
