igor_vitrenko [27]

Length 7 feet and Width 5 feet

Step-by-step explanation:

we know that

The area of the rectangle ( a dining room table) is equal to

A=LW

where

L=(3x+1)\ ft

W=(3x-1)\ ft

A=35\ ft^2

substitute

35=(3x+1)(3x-1)

Apply difference of squares right side

35=9x^2-1

9x^2=36\\x^2=4\\x=\pm2

Remember that the length cannot be a negative number

so

x=2

<em>Find the length</em>

L=(3(2)+1)=7\ ft

<em>Find the width </em>

W=(3(2)-1)=5\ ft
