a rectangler table is 2xs as long as it is wide. if the area is 72ft squared, what is the length and the width

Answer 1

(2b) (b) = 72
b² = 36
b = 6
breadth = 6 ft
length = 12 ft

Answer 2

Length = 2w
Width = w

Area = L x W
Then substitute:
72 = 2w x w
72/2 = 2w x w /2
36 = w x w
36 = w^2
Squareroot:
6 = w
Therefore:
72 = 2(6) x 6
72 = 12 x 6
12 = L

Answer 3

Let width be x then length = 2x
length*width = area
2x*x = 72
x*x= 36
x= 6
width=6 and length = 2*6 =12

Answer 4

the length is 12 and the width is 6.

2x(x)=72
2x²=72
x²=36
x=6

2x(or length)=2(6) or 12.
x=6 (width)
