A rectangular floor is covered by a rug except for a strip Y meters wide along each of the four edge. If the floor is P meters by Q meters, what is the area of the rug in square meters?  Choose the correct answer
A) 4(P-2Y)(Q-2Y) B) 3(P-2Y)(Q-2Y) C) (P-2Y)(Q-2Y) D) (P-2Y)(Q-2Y)/3 E) (P-2Y)(Q-2Y)/4
A strip of Y meters is covering the inner rectangular rug for all 4 sides.   Length of inner rug = P-(2Y)   breadth of inner rug= Q-(2Y)   Area of Rug= (P-2Y)(Q-2Y)   Ânswer: (P-2Y)(Q-2Y)
