Calculating the Area of an Irregular Four-Sided Lot

Estimating Square Footage and Acres for a Non-Rectangular Parcel

Your lot has four unequal sides (92.94 ft front, 167.40 ft rear, 187.58 ft and 148.40 ft sides) with no parallel sides—this is an irregular quadrilateral, not a trapezoid.

Area Calculation

Without angle measurements, the exact area cannot be determined; it varies between a minimum and maximum. Using the given side lengths, the maximum possible area is approximately 19,814 sq ft (0.455 acres). For practical purposes (seed, fertilizer), treat it as half an acre to ensure adequate coverage.

Getting Precise Measurements

• Check your county's survey maps (plats) at the recorder's office—they're accurate to inches.
• Hire a surveyor for a current plat if you need exact figures for construction or legal purposes.

For lawn care, the half-acre estimate with a small surplus is safe and practical.
