Omari Thomas · Answer 1

Step-by-step explanation:

Width = x

Length = 2x+5

Area = length * breadth

42=x (2x+5)

42=2x^2+5x

0=2x^2+5x-42

Solve for X.

The positive value is the answer because the length cannot be a negative value.

Then substitute the x value to get the length and the breadth.
