<u><em>The question in English is</em></u>
The area of a basketball court is 420 m² if the length is 14 meters more than the width, what are its dimensions?
Let
L ----> the length of the basketball court
W ---> the width of the basketball court
we know that
The area of the of rectangular court is

we have

so
----> equation A
----> equation B
substitute equation B in equation A and solve for W

Solve the quadratic equation by graphing
The solution is 
see the attached figure
Find the value of L

therefore
The dimensions are
The length is 28.656 m and the width is 14.656 m
