Question

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

Answer 1

Answer:

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
