The length of a rectangle is six times its width. If the area of the rectangle is 294 ft^2, find its perimeter.

X=7

Step-by-step explanation:

Since area of a rectangle is 294

Area of a rectangle=length×breadth

Let's the width be x

Since length is 6 times of width=6x

Area=l×w

294=x×6x

294=6x^2

Divide both sides by 6

x^2=49

Square root both sides

x=7

Therefore x is 7

answer: there are x+184 pages in olivia's book.

step-by-step explanation:

let the total number of pages in the book which olive has already read be x.

then if olive has 184 pages left to read, then the total number of pages are in olive's book= pages she has read+pages she has left to read

therefore, the total number of pages in olivia's book=

hence, there are x+184 pages in olivia's book.
