The length of a rectangular mural is 2ft. more than three times the width the area is 165 sq. ft. Find the Width And Length

olga nikolaevna [1]

We know that the formula for the area of a rectangle is:

$A=lw$

We know that the area is 165. Now we need to solve for the dimensions.

Let the width of the rectangle be " $x$ "

Then the length of the rectangle is $3x+2$

Substitute.

$(3x+2)(x)=156$

Multiply the terms.

$3x^2+2x=156$

Bring the 156 over.

$3x^2+2x-156=0$

We have to use the quadratic formula to solve this now. Let us restate it:

$x= \frac{-b± \sqrt{b^2-4ac} }{2a}$

Now I'm going to fast forward this because all the rest is boring stuff and substitution. The answer is:

$\frac{ \sqrt{469}-1 }{3}$

Since we cannot have a negative answer, we must cancel out the other answer, which I did not include.

Hope this helped! :)
