The perimeter of a rectangle is the sum of the lengths of its four sides. which expression where

The expression which show the perimeter of rectangle is  

2 ( Length + Breadth )

Step-by-step explanation:

Given as :

The measure of the length of the rectangle = L unit

The measure of the breadth of the rectangle = B unit

For any rectangle the opposite two sides are equal

And The rectangle has four sides

Let the Two opposite side be length

And The other two opposite side be breadth

Now, Perimeter

The perimeter is define as the sum of all sides of any polygon

Since the rectangle has four sides , with two opposite sides equal

∴ Perimeter of rectangle = Length + breadth + length + breadth

or,  Perimeter of rectangle = L + B + L + B

Or,  Perimeter of rectangle = 2 times L + 2 times B

Or,  Perimeter of rectangle = 2 times ( L + B )

Or,  Perimeter of rectangle = 2 ( Length + Breadth )

Hence The expression which show the perimeter of rectangle is                    2 ( Length + Breadth )  . Answer

sin3a=12/15

step-by-step explanation:

since one side was multiplied by 3 the other side must also be multiplied by 3.
