Answer» Step-by-step explanation: Length of RECTANGLE is reduced by 5 units and its breadth is increased by 3 units and the AREA of rectangle is reduced by 8 sq. units (L−5)(W+3)=LW−8 LW+3L−5W−15=LW−8 3L−5W=7 __(1) Length is reduced by 3 units and breadth is increased by 2 units, then the area of Rectangle will be 67 sq. units increased (L−3)(W+2)=LW+67 LW+2L−3W−6=LW+67 2L−3W=73 __(2) Solving (1)×2 by (2)×3 2(3L−5W=7)→6L−10W=14 3(2L−3W=73)→6L−9W=219 −W=−205 W=205 W = 205 in eq (1). 3L−5(205)=7 3L=7+1025 3L=1032→L= 3 1032
