# What is the perimeter of a square with the side 50x cm?

## 21x cm    30x cm    200x cm    100x cm Hint:

## The correct answer is: 200x cm

### The given value for the length of the side of a square is 50x cmLength = 50x cmWe have to find the perimeter of a square. We know that perimeter means the total length of the boundary of the shape. As a square has four equal sides, we will have to add them to get the length of complete boundary, or in other words a perimeter. As square has all sides equal. So to find a perimeter we will have to add the side 4 times, or simply multiply the side by 4.The formula for the perimeter of a square will bePerimeter = 4(length)Substituting the respective values, we getPerimeter = 4(50x)As there are two with the same variable, we can add them directly like normal numbers.Perimeter = 200x cmTherefore, the perimeter of the square will be 200x cm.So option which is ‘200x cm’, is the right option.

For such questions, we should be knowing the formulas of area and shapes of different shapes. We also have to be careful if we are dealing with same variables or different variables before performing operations.
