Question

A room’s floor is y meters long. It’s width is 5 meters shorter. If the perimeter of the floor is (4y + 1) meters, can you solve for it’s length?

Answer 1

We know that the perimeter of a rectangle is:

$P=2L+2W$ (1)

Where:

P is the perimeter

L: it's the long

W: is the width

They tell us that the perimeter is:

(4y + 1)

The long is y

The width is y-5.

Then we can write equation (1) as follows:

$(4y + 1)=2y+2(y-5)$

$4y+1=4y-10$

$1 = -10$

The equation can not be solved and, therefore, it is not possible to find the value of "y" with the information provided.
