(a) To find the length of the parking lot, we can use the formula for the area of a rectangle: Area = Length x Width. We are given the area and the width, so we can rearrange the formula to solve for the length: Length = Area / Width. Plugging in the given values, we have: Length = 8019 m^2 / 81 m = 99 m. Therefore, the length of the parking lot is 99 m.(b) To find the width of the pool, we can use the formula for the perimeter of a rectangle: Perimeter = 2(Length + Width). We are given the perimeter and the length, so we can rearrange the formula to solve for the width: Width = (Perimeter / 2) - Length. Plugging in the given values, we have: Width = (342 m / 2) - 92 m = 79 m. Therefore, the width of the pool is 79 m.
