Answer:

98 inches

6x^2=294

x^2=49

x=7

2*7+2*42= 14+84=98 inches

length the width be= W

let the length be =6×W=6W

area = length ×width

294=6W × W

294= 6w^2

49=w^2

the square root of 49 is 7

so the width is 7

while the length is 7 ×6=42

perimeter=2(L+W)

p=2(42+7)

p=2(49)

p= 98

w - width

6w - length

486 in² - area of the rectangle

(w)(6w) = 6w² - area of the rectangle

The equation:

6w² = 486 divide both sides by 6

w² = 81 → w = √81

w = 9 in

l = 6w → l = (6)(9) → l = 54 in

The perimeter: P = 2l + 2w

P = 2(54) + 2(9) = 108 + 18 = 126 in

The perimeter is 126inX=7

Since area of a rectangle is 294

Area of a rectangle=length×breadth

Let's the width be x

Since length is 6 times of width=6x

Area=l×w

294=x×6x

294=6x^2

Divide both sides by 6

x^2=49

Square root both sides

x=7

Therefore x is 7

Do 600 divided by 6 and it will equal 100 so you answer is 100L = 6wA = 216

A = lw

216 = (6w)(w)

216 = 6w^2

216/6 = w^2

36 = w^2

w = 6

l = 6(6)

l = 36

P = 2l + 2w

P = 2(36) + 2(6)

P = 72 + 12

P=84Rectangle area = a*b

perimeter = 2(a+b)

a - lenght

b - width

a = 6b

a*b=600

6b*b=600

b=10

a = 6*10 = 60

Perimeter = 2(a+b)=2(60+10)=2*70=140 ydSolutions = 504 answerWidth= w

lenght = 6 width = 6w

area= 284 yd²

= (width)(length)

= (w)(6w)

= 6w²

6w²= 284

w²= 284/6

= 47.333333

w=√47.2

= 6.88 inches

perimenter = 2width+ 2 lenght

= 2(w) + 2(6w)

= 2w+12w

= 14w

= 14(6.88)

= 96.28 inches
