Question
The length of a rectangle is 4 less than twice the width. The area of the
rectangle is 70 square meters. Find the dimensions of the rectangle.
Answer:
Width: 7 Length: 10
Step-by-step explanation:
Width: x
length: 2x-4
Area: 70 meters squared
(2x-4)x=70
2x^2-4x=70
2x^2-4x-70=0
2(x^2-2x-35)=0
(x-7)(x+5)=0
x cannot be negative so x=7
