Question

the distance around a rectangular field is 400 m the length of the field is 26 metres more than the breadth calculate the length and breadth of the field

Answer 1

perimeter of rectangular Field=400m

let breadth of the field =x
then length of the field =26

perimeter of rectangular Field=2(length+breadth)

2(x+x+26)=400
2x+26=200
2x=174
x=87

breadth=87m

length=87+26=113m

____________________

Answer 2

400=2(l+26+l)
200-26=2l
174/2=l
87=l
87-26=61=b
this is the answer
