A rectangular paper, when folded into two congruent parts had a perimeter of 34 cm for each part folded along one set of sides and the same is 38 cm when folded along the other set of sides. What is the area of the paper? Choose the correct choice.
A) 140 cm2	B) 240 cm2	C) 560 cm2	D) 160 cm2	E) None of these
When folded along breadth, we have :   2(l⁄2 + b) = 34 or l + 2b = 34 ....(i)   When folded along length, we have :   2(l + b⁄2) = 38 or 2l + b = 38 ....(ii)   Solving (i) and (ii), we get :   l = 14 and b = 10.   ∴ 140 cm2rea of the paper = (14 × 10) cm2 = 140 cm2   140 cm2nswer 140 cm2
