Question

9. Length of a rectangle is 6 cm more than its width. If its length and breadth each is decreased by
3 cm, the area of new rectangle is decreased by 36 sq cm. Find the original length and breadth of the
original rectangle
​

Answer 1

Answer:

216

Step-by-step explanation:

L = B+6 …(1)

L+B = 60/2 = 30, or

L = 30-B …(2)

Equate (1) and (2)

B+6 = 30-B, or

2B = 24, or B = 12 so L = 18 cm.

The length = 18 cm, breadth = 12 cm and the area = 216 sq cm.
