Question

The perimeter of a rectangle is 9 times its breadth its length is 3cm more than twice its breadth find the dimensions

Answer 1

Length = 7 cm, breadth = 2 cm

Given:

The perimeter of a rectangle is 9 times its breadth.

Its length is 3 cm more than twice its breadth.

To find:

The dimensions

Step-by-step explanation:

Let, breadth = x cm

Then length = (2x + 3) cm

So, perimeter = 2 (x + 2x + 3) cm = (6x + 6) cm

According to the question,

6x + 6 = 9x

⇒ 3x = 6

⇒ x = 2

So, breadth = 2 cm

and length = (2 × 2 + 3) cm = 7 cm
