Problema Solution
A rectangular table is four times as long as it is wide. If the area is 196ft squared , find the length and the width of the table
Answer provided by our tutors
let
l = the length of the table, l>0
w = the width of the table, w>0
rectangular table is four times as long as it is wide
l = 4w
the area is 196 ft squared
l*w = 196
plug l = 4w into the last equations
4w*w = 196 divide both sides by 4
w^2 = 49
w = 7 ft
l = 4*7
l = 28 ft
the length of the table is 28 ft.
the width of the table is 7 ft.
