Answer:

b = 15m; l = 25m

Explanation:

let breadth of the field be x m

according to statement- length = (10+x)m

perimeter = 80m

therefore, 2(l + b) = 80

2(x+10+x) = 80

2(2x+10) = 80                                      

2x+10 = 40                                   (dividing both sides by 2)

2x = 40-10 = 30

therefore, x= 30/2 = 15m

hence, length = 15+10 = 25m

answer - breadth = 15m

length = 25m
