Solve for X: Rectangle with Width 8cm and Area 32cm²

Question

The width of a rectangle is equal to
$8$ cm and its length is $x$ cm.

The area of the rectangle is $32$ cm².

Calculate $x$ .

00:00 Calculate X

00:03 Let's use the formula for calculating rectangle area (side times side)

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

00:12 Isolate X

00:15 And this is the solution to the question

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

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

$32=8x$

Let's now reduce both sides of the equation by the (HCF) highest common factor 8:

$x=4$
