Question

the perimeter of a rectangular field is 360 m and its breadth is 75m.Find its length.

Answer 1

perimeter of rectangle=360m
2(l+b)=360
2(75+b)=360
75+b=360/2
75+b=180
b=180-75
b=105
BREADTH =105metre

Answer 2

perimeter of rectangular field=2(l+b)
360=2(l+75)
360=2l+150
360-150=2l
210=2l
l=210/2
l=105
hence length=105m
