the length of a rectangle is six times its width. if the area of the rectangle is 294 cm^2, find its perimeter.

Step-by-step explanation:

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

50 min

step-by-step explanation:

they will be decreasing both their times in half

60 / 2 = 30

40/2 = 20

30 + 20 = 50
