Question

a rectangular table is six times as long as its width. If the area is 54ft squared (54^2), find the length and the width of the table.

Answer 1

Length X width = 54

6w x w = 54

6w^2=54

w^2=9

w=3

l = 6w = 18

Thus length is 18 feet, and width is 3 feet.

Answer 2

l=18ft

w=3ft

l = 6w

w x 6w = 6w^2

6w^2=54

(/6)  w^2=9

(square root)  w=3

3 x 6 = 18 = l
