Question

The perimeter of a rectangle is 28 cm and its length is 8cm find its breadth​

Answer 1

Answer:

t is given that,

Length of a rectangle = 36 cm.

Breadth of a rectangle = 28 cm.

We know that,

Perimeter = 2(l+b)

Substituting the values,

=2(36+28)

=2(64)

=128 cm.

It is given that,

Perimeter of a square = Perimeter of a rectangle = 128 cm.

So the side of square = perimeter/4

Substituting the value,

=128/4

=32 cm.

Answer 2

Step-by-step explanation:

perimeter of rectangle is 2(l+b)

2(8+b)=28

transporting 2 RHS

8+b=28/2=14

transporting 8 to RHS

b=14-8

b=6
