Question

the length of rectangle is greater than the breadth by 18cm. if length and breadth are incredibly by6 cm, it's area increased by 168 cc. what is the length and breadth of rectangle.

Answer 1

Answer:

Length = 20 cm

Breadth = 2 cm

Step-by-step explanation:

It is given that

The length of rectangle is greater than the breadth by 18cm.

Let x be the breadth  of rectangle , then

Length = x + 18

Area of rectangle = Length x breadth =x(x + 18)

if length and breadth are incredibly by6 cm, it's area increased by 168 cc

New length = x +24

Breadth = x + 6

New area becomes (x + 24)(x +6) = x(x + 18) + 168

x^2 + 30x + 144 = x^2 + 18x + 168

x = 2

Therefore Breadth = 2cm and Length = 20cm
