Question

if length and breadth of rectangle are double and half respectively the what is its area

Answer 1

Area of a rectangle = Length ×× BreadthLet the length of the rectangle = lBreadth = bArea = l×b=lbl×b=lb -----(1)Given Lenght is halved ⇒l2⇒l2Breadth is doubled = 2×b=2b2×b=2bArea = l2×2b=lbl2×2b=lb -------(2)Hence Equation (1} = Equation (2}⇒⇒ Area Remains the same
