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.

Respuesta :

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
