Question

The length of a rectangle exceeds its breadth by 4cm. If the length and breadth are each increased by 3cm, the area of the new rectangle is 81cm

Answer 1

Answer:

The length and breadth are 14 cm and 10 cm

Step-by-step explanation:

Given that the length of a rectangle exceeds its breadth by 4 cm .if length and breadth are each is increased by 3 cm , the area of the new rectangle is 81 square cm more than the given rectangle.

we have to find the length and breadth of rectangle.

Let the breadth of rectangle be x cm

∴ The length is x+4

Now, length and breadth are each is increased by 3 cm

New length=(x+4)+3=x+7

New breadth=x+3

As the area of the new rectangle is 81 square cm more than the given rectangle.

⇒

∴

The length and breadth are 14 cm and 10 cm
