Question 198594
The length of a rectangular field is 2 m greater than three time sits width. The area of the field is 1496 m^2
Here we go
{{{l=3w+2}}}
{{{1496=lw}}}
{{{1496=(3w+2)w}}}
{{{1496=3w^2+2w}}}
Quad Form
{{{x = (-b +- sqrt( b^2-4*a*c ))/(2*a) }}} where a=3, b=2, c=-1496
Real solutions:
Root 1: -22.6666666666667
Root 2: 22

A negative answer is not usable, therefore 22m is the width
{{{l=3(22)+2}}}
{{{l=66+2}}}
{{{l=68}}}
{{{1496=(22)(68)}}}
{{{1496=1496}}}
