a rectangular patio has a length of 12 1/2 feet and an area of 103 1/8 square feet .what is the width of the patio?
jok3333 [9.3K]
L=Length of the rectangular patio

A=Area of the rectangular patio

W=Width of the rectangular patio

f=foot

------------------------------------

L=25/2f

A=(103+1/8)f²=(824/8+1/8)f²=825/8f²

-----------------------------

Now, A=L*W=825/8f²

-------------------------------

<em>USE BODMAS</em>

Therefore:

25/2fW=825/8f²

So...

W=(825/8f²)/(25/2f)

=33/4f
