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.
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
