413.
The perimeter of a rectangular field is 120 metres. If its breadth is 27 metres, find its length​

Answer 1

Answer:

12. 32 m

13. 33 m

Step-by-step explanation:

12.  Let breath be b,

     2(l + b) = 164

     2(50 + b) = 164

     100 + 2b = 164

     2b = 164 - 100

     2b = 64

     b = 64/2

     b = 32 m

13. Let the length be l,

    2(l + b) = 120

    2(l + 27) = 120

    2l + 54 = 120

    2l = 120 - 54

    2l = 66

    l = 66/2

    l = 33 m
