Rectangle Area Problem: Calculate AB When Area = 44 and AC = 4

Question

The area of the rectangle below is equal to 44.

AC = 4

Calculate AB.

00:00 Determine the value of AB

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 proceed to solve for AB

00:13 This is the solution

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

Let's begin by substituting the known data into the formula:

$S=AB\times AC$

$44=AB\times4$

Let's now divide both sides by 4:

$AB=11$
