Question

# Find the perimeter of the rectangle if the length and breadth are 2x and 3x, respectively.

Hint:

## The correct answer is: 10x

### The given values for length and breadth of rectangle are given.Length = 2xBreadth = 3xWe have to find the perimeter of a rectangle. We know that perimeter means the total length of the boundary of the shape. As a rectangle has four sides, we will have to add them to get the length of complete boundary, or in other words a perimeter. Rectangle has opposite sides equal. So to find a perimeter we will have to take length and breadth twice.The formula for the perimeter of a rectangle will be Perimeter = 2( length + breadth )Substituting the respective values, we getPerimeter = 2(2x+3x)As there are two with the same variable, we can add them directly like normal numbers.Perimeter = 2(5x)Perimeter = 10x unitsTherefore, the perimeter of the rectangle will be 12x units.So option (d), which is ‘10x’, is the right option.

The main part of such questions is to find the relation between the variables. For that, we have to remember the formulas properly.
