The area of a rectangle is 35 ft2 and the length of the rectangle is 3 At more than double the width. Find the dimensions of the rectangle.

Respuesta :

Answer: Width: 3.5 Length:10

Step-by-step explanation:

width=x

length=2x+3

area=35

x(2x+3)=35

2x^2+3x=35

2x^2+3x-35=0

(2x-7)(x+5)=0

x obviously cannot be negative ,so x=3.5
