Problema Solution
Gabriella wants to tile a room with an area of 320 square feet. The width of the room is 4/5 its length. What are the length and width of the room?
Answer provided by our tutors
let
l = the length of the room, l>0
w = the width of the room, w>0
A = 320 ft^2 the area of the room
The width of the room is 4/5 its length:
w = (4/5)l
the area of the room A = l*w
l*w = 320
plug w = (4/5)l into the last equation:
l*(4/5)l = 320
by solving we find:
l = 20 ft
click here to see the step by step solution of the equation:
w = (4/5)*20
w = 16 ft
the length is 20 ft and the width is 16 ft.
