Question

perimeter of a rectangle is 56.8 its length is8 its what is breadth.​

Answer 1

Answer:

the breath is 20.4

Step-by-step explanation:

perimeter of a rectangle =2(l+b)

perimeter = 56.8

length = 8

let breath be b

then, 56.8 = 2(8+b)

56.8/2 = 8+b

28.4 = 8+b

28.4 -8= b

b = 20.4

therefore the breath is 20.4

Answer 2

Given:

Perimeter of the rectangle = 56.8 sq.units

Length of the rectangle = 8 units

To Find:

The breadth of the rectangle.

Formula:

Perimeter of a rectangle = 2 ( L + B )

where, L means Length and B means Breadth.

Solution:

According to the question,

Perimeter of the rectangle = 56.8 sq.units

2 ( 8 + B ) = 56.8 sq.units

16 + 2B = 56.8 sq.units

By transposition method, we get

2B = ( 56.8 - 16 ) units

B = ( 40.8 / 2 ) units

B = 20.4 units

Answer:

The breadth of the rectangle is 20.4 units.
