This lot has the shape of a trapezoid. Regard the 2 different lengths as 160' and 80' and the width 100'
Applying the formula for the area of a trapezoid:
80' + 160'
A = ----------------- * 100' = 24000 ft^3
2
Let
the length = x
the width = x-23
perimeter = 122 ft
perimeter = 2 ( length + width )
122 = 2 ( x + x-23)
122 = 2x + 2x - 46
122=4x-46
122+46=4x
168=4x
x=168/4
x=42
length=42
width = x -23
= 42-23
= 19
