The length of the rectangle is 4 meters less than twice its widdth. the area of the rectangle is 70. find the dimensions of the rectangle

Width = 7m

Length = 10 m

Step-by-step explanation:

Width = w

Length = 2w - 4

Area = 70

length * width = 70

(2w - 4) * w = 70

2w*w - 4*w = 70

2w² - 4w -70 = 0

2w² - 14w + 10w - 10*7 = 0

2w (w - 7) + 10(w - 7) = 0

(w-7) (2w+10) = 0

w - 7 = 0           {Ignore 2w + 10,as measurement will not come in negative}

w = 7 m

length = 2w -4 = 2*7 - 4 = 14 -4 = 10 m

i got 86 for this

hope this !

if you need an explanation just ask

hello :

by applying the distributive property :

6 × 4.3 = 6 × ( 4 + 0.3 )

            =   (6 ×   4) + (6 ×   0.3)

            = 24 + 1.8

6 × 4.3 = 25.8
