a rectangle table is five times as long as it is wide if the area is 245ft2, find the length and the width of the table
width is ___?
length is ___?

Answer 2

you have 2 equations and 2 unknowns
length x width = 245 ft^2
length = 5*width

so you sub the second equation into the first to get
(5* width) * width = 245

and solve for width

5*width^2 = 245
width^2 = 245/5
width = sqrt(49)
width = 7 ft

now you sub that back into the second equation and get
length = 5 * 7
length = 35 ft
