The length of a rectangle is 3 in more than twice it’s width, and it’s area is 65 sq in. What is it’s width?

likoan [24]

Answer: 5 inches.

Step-by-step explanation:

The formula for calculate the area of a rectangle is:

$A=w*l$

Where l is the length and w is the width.

If the length of a rectangle is 3 inches more than twice it’s width, then:

$l=2w+3$

Substitute $l=2w+3$ and the area into the formula and solve for the width:

$65=(2w+3)w\\65=2w^2+3w\\0=2w^2+3w-65$

Use the quadratic formula:

$w=\frac{-b\±\sqrt{b^2-4ac}}{2a}\\\\w=\frac{-3\±\sqrt{3^2-4(2)(-65)}}{2(2)}\\\\w=5\\w=-6.5$

Choose the positive value.

Therefore, the width is: 5 inches.
