Question

Length of a rectangle is 2 cm more than twice its breadth. If the perimeter of the rectangle is 34
cm, find its length and breadth.
er is 160 cm and its length is 10 cm more than its
Exa​

Answer 1

Answer:

Length = 12 cm

Breadth = 5cm

Step-by-step explanation:

Let the length of the rectangle be 'x' cm

and breadth be 'y' cm respectively.

A/Q,

=> x(length) = (2y + 2) cm ---> (1)

Now,

Perimeter of the rectangle = 2(l + b)

=> 34 = 2(x+y)

Putting the value of'x'

=> 34 = 2(2y + 2 + y)

=> 34 = 2(3y + 2)

=> 34 = 6y + 4

=> 30 = 6y

=> y = 5 cm

Now, putting the value of 'y' in equation (1) we get

=> x = 2y + 2

=> x = 2(5) + 2

=> x = 12 cm

Hence,

Length = 12 cm

Breadth = 5cm
