Calculate Rectangle Side Length: Area 50 with Height 5

Question

The area of the rectangle below is equal to 50.

AC = 5

How long is side AB?

00:00 Find AB

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

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

00:11 And this is the solution to the problem

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

Let's first input the given data into the formula:

$S=AB\times AC$

$50=AB\times5$

Let's now divide both sides by 5:

$AB=10$
