Problema Solution
marios living room has a length 6 feet wider than the width. The area of the living room is 280 square feet. What are the dimensions of the living room?
Answer provided by our tutors
Let
x = the width of the room, x>0
x + 6 = the length of the room
A = 280 ft^2 the area of the room
Since A = width*length we have:
x(x + 6) = 280
........
click here to see the equation solved for x
........
x = 14 ft
We need to ignore the negative solution -20 since the width can not be negative.
14 + 6 = 20 ft
The dimensions of the room are: the length is 20 feet and the width is 14 feet.
