Rectangle Area Problem: Find Width AB When Area = 75 and Height = 7.5

Question

The area of the rectangle is equal to 75.

AC = 7.5

Calculate AB.

00:00 Find AB

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

00:08 We'll substitute appropriate values according to the given data and solve for AB

00:13 And this is the solution to the question

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

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

$S=AB\times AC$

$75=AB\times7.5$

Let's now divide both sides by 7.5:

$AB=10$
