Question

the length of a square field and a rectangular field are 80 metre and 100m respectively if perimeter of both field is same find the breadth of rectangle field ​

Answer 1

Step-by-step explanation:

1) perimeter of sq = 4×80

= 320 m

P of rec = 2(l+b)

320. = 2(80+b)

= 2×80 + 2b

= 160 +2b

2b = 320-160

b = 60/2

= 30m

Answer

Breadth = 30m
