A rectangle with perimeter 88 m is cut into 5 congruent rectangles as shown in the diagram. The perimeter of each of the congruent rectangle is
Options:
A .  80
B .  40
C .  120
D .  none of these
Answer: Option B : B Here AD = BC, 3a = 2b, a=2y, b=3y The Perimeter of rectangle =4b +5a =4 x 3y + 5 x 2y = 22y; 22y =88; y =4; a =8 and b =12; The perimeter of each of the congruent rectangle = 2(a+b) =40; Option (b).
