Solve for X: Rectangle Area 27 with Side Length 3X

Question

The area of the rectangle is equal to 27.

AC = 3

AB = 3X

Calculate X.

00:00 Calculate the value of X

00:03 The formula for calculating the area of a rectangle is width(AB) multiplied by length(AC)

00:07 Substitute in the relevant values according to the given data and solve for X

00:14 This is the solution

The area of a rectangle is equal to the length multiplied by the width.

Let's insert the known data into the formula:

$27=3\times3x$

$27=9x$

Lastly let's divide both sides by 9:

$x=3$
