Question

the perimeter of rectangle is 15 whole 3 upon 7 metre and its length is 4 whole 2 upon 7 metre find its breadth ​

Answer 1

Answer is 3 whole 3 upon 7 meter.

Explanation:

Perimeter=2(l+b)

So, 15whole3/7 = 2(4whole2/7 + b)

I.e., 108/7 = 2(30/7 + b)

108/7 = 60/7 + 2b

108/7 = (60+14b)/7

108 = 60+14b [7 and 7 gets canceled]

14b=48

b = 24/7

b = 3whole3/7

Hope you get it...like it if yes...
