Problema Solution
The length of the top of a table is 2 m greater then the width. The area is 80 m^2. Find the dimensions of the table.
Answer provided by our tutors
Let
x = the width, x>0
x + 2 = the length (2 m greater than the width)
A = 80 m^2 the area
Since the area of a rectangle A = width*length we have:
A = x*(x + 2)
x(x + 2) = 80
........
........
x = 8 m
x + 2 = 8 + 2 = 10 m
The length of the table is 10 meters.
The width of the table is 8 meters.
