Question

The length of a rectange is 7cm less than twice its breadth . If the length is decreased by 2cm and breadth is increased by 3cm the perimeter resulting rectangle is 66cm . Find the length and breadth of original rectangle

Answer 1

L= 2B-7

2(L-2)+2(B+3)=66
replacing L
2(2B-9)+2B+6=66
6B= 78
B=13

original dimensions breadth 13 cm length 19cm
