A rectangular field is 3.2 yards long. A fence marking the boundary is 11.2 yards in length. What is the area of the field in square yards?
(A) 4.68
(B) 7.68
(C) 9.28
(D) 11.28
(E) 12.38
Rectangular field length = 3.2 yards
A fence making boundary means the perimeter of the rectangular field = 11.2 yards
i.e. \(2*(Length + Breadth) = 11.2\)
or \(2* (3.2 + Breadth) = 11.2\)
or breadth = \(2.4 yards\)
Now area of the field = \((Length * breadth) = 2.4 * 3.2 = 7.68\)
