Calculate EB Length When EB = 1/5 AB in a Rectangle with Area 70

Question

The area of the rectangle is 70.

$EB=\frac{1}{5}AB$

Calculate the length of EB.

00:00 Find EB

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

00:09 Let's substitute appropriate values and solve for AB

00:19 This is the size of AB

00:22 EB equals one-fifth of AB according to the given data

00:26 And this is the solution to the problem

The area of rectangle ABCD equals its length multiplied by its width.

Let's substitute the known values into the formula:

$70=7\times AB$

Now let's divide both sides by 7:

$AB=10$

Since we know that EB equals one-fifth of AB, we can use the known data to calculate side EB as follows:

$EB=\frac{1}{5}AB=\frac{1}{5}\times10=2$
