Area of rectangle (A) = length (l) times width (w)
length = width + 16 and area = 161
Replacing this number to the above equation
161 = (width + 16) * width
161 = width^2 + 16*width
width^2 + 16*width -161 = 0
(width - 7)*(width + 23) = 0
width = 7 or width = -23
Since the width can't be negative, the actual width = 7
the length = 7 +16= 23
The dimension is 23 meter by 7 meter
