Let the breadth be x then length will be (2x+1). Area of rectangle = length x Breadth => x(2x+1) = 28 Solve for x and find the length and breadth

Wait, You will get an equation \(\sf 2x^2 +x-28 = 0\)

Now, you need to solve this quadratic equation. You will get two values for x, one positive and one negative.

so i solve for x

Yes, You can use this website to check your value of x http://www.math.com/students/calculators/source/quadratic.htm

Note:- You need to pick the positive value. The value of x will be your breadth and the length will be 2x+1
