Question

If length of rectangle is 4 unit and perimeter is 20 units. Find its bredth.

Answer 1

Answer:

6 units

Step-by-step explanation:

formula for finding the breadth: (20- (4*2)) /2

                  = (20-8)/2

                  = 12/2

                  = 6

Answer 2

☆ Solution ☆

Given :-

• The length of the rectangle is 4 unit.

• The perimeter of the sentence is 20 unit.

To Find :-

• The breadth of the rectangle.

Step-by-Step-Explaination :-

Let,

• The breadth of the rectangle be x .

As we know that :-

Perimeter of the rectangle = 2 ( length + breadth )

Where,

• Perimeter of the rectangle = 20 unit

• Length of the rectangle = 4 unit

• Breadth of the rectangle = x

Putting the respective value,

20 = 2 ( 4 × x )

20 = 8 × 2x

20 - 8 = 2x

12 = 2x

x = 12/2

x = 6

Hence,

The breadth of the rectangle is 6 unit .
