34 divided 5323 in simple form
joja [24]

The value when 34 is divided by 5323 is 0.00639.

<h3>What is division?</h3>

It should be noted that division simply means the opposite of multiplication. It represents the way numbers are combined in order to make new numbers.

The steps include:

1: Take the dividend's first digit starting from the left in step one. Verify if this digit exceeds or is equal to the divisor.

2. Next, divide it by the divisor, and write the result as the quotient on top.

3. Subtract the outcome from the digit, and then put the difference below.

4: Decrease the dividend's subsequent digit (if present).

5: Carry out Step 4 again.

In this case, 34 divided 5323 will be 0.00639. It should be noted that this illustrates a decimal.

Find the area and perimeter.
yan [13]

Answer:

Area = 33√3

Perimeter = 122

Step-by-step explanation:

This is a parallelogram and perimeter for a parallelogram is calculated by adding side length to base and that's multiplied by 2

perimeter (6 + 11) × 2 = 122

The area is calculated by multiplying height to the base

there's a 30° 60° 90° special triangle inside the parallelogram and the side length that sees 60° in this special triangle is 3√3 so this is our height and base is given as 11

Therefore the area of this parallelogram is

3√3 × 11 = 33√3
