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

it is not letting me

anonymous · Answer

nevermore i'll just get this one wrong

abhisar · Answer

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

abhisar · Answer

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

anonymous · Answer

so i solve for x

abhisar · Answer

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

abhisar · Answer

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