Question

The length of a rectangle exceeds its breadth by 7cm. If the length is deceased by 4cm and the breadth is
increased by 3cm, the area of the new rectangle is the same as the area of original rectangle. Find the length and
breadth of the original rectangle​

Answer 1

Answer:

Step-by-step explanation:

B =x

L= x+7

Original Area =x×(x×7)=x^2+7x

New length =x+7-4=x+3

New breadth =x+3

New area =(x+3)(x+3)=x^2+6x+9

A2Q

=x^2+7x =x^2+6x+9

=x^2- x^2+7x=6x+9

=7x-6x=9

=x=9cm=Breadth

9+7=16cm=Length
