The length of a rectangle is 2 cm more than its breadth,and its perimeter is 28 cm find the length and breadth of the rectangle

Answer»

ANSWER:

Length is 8cm and breadth is 6CM.

Step-by-step EXPLANATION:

Given that:

  • Let breadth = x cm
  • length = (x+2)cm

Because length is 2 cm more than a breadth.

  • Perimeter = 28 cm.

To find:

  • the length and breadth of the rectangle.

Formula to know:

Perimeter of rectangle = 2(length+breathe)

Solution:

2(l+b) = 28

=> 2(x+x+2) = 28

=> 2(2x+2) = 28

=> 2x+2 =$\mathrm{\frac{28}{2}}$

=> 2x+2 = 14

=> 2x = 14-2

=> 2x=12

=> x = 12/2

=> x = 6cm.

Now,

Length = x+2 => 6+2 = 8cm.

Breathe = x => 6cm. ANS.
