Q. no. 8
Given,
Perimeter of rectangle = 15 3/7 m
= 108/7 m
length of rectangle = 4 2/7 m
= 30/7 m
we KNOW that, ( LET the breadth be n)
Perimeter of rectangle = 2 (length+breadth)
108 / 7 = 2 ( 30/ 7 + n )
108/ 7 = 60/ 7 + 2n
2n = 108/ 7 - 60/ 7
n = 48/ 7 divided by 2/ 1
n = 48/ 7 multiplied by 1/ 2
n = 24/ 7
