Solve for X: Rectangle Area 48 with Height 4 and Width 2X

Question

The area of the rectangle below is equal to 48.

AC = 4

AB = 2X

Calculate X.

00:00 Find X

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

00:07 Let's substitute appropriate values according to the given data and solve for X

00:14 And this is the solution to the question

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

Let's begin by presenting the known data:

$48=4\times2x$

$48=8x$

Lastly let's divide both sides by 8:

$x=6$
