Question: how do i calculate how much grass i need?
Answer: Calculate the quantity of grass you need. Rectangle or square: Multiply the width times the length for total area. For example: 50 ft x 70 ft = 3500 sq ft. Triangle: Multiply the base times the height, and then divide by 2 (area = base x height / 2). For example: 10 ft x 20 ft = 200 ft / 2 = 100 sq ft.
