Final Answer:

(a) The area of Lashonda's patio in square meters is approximately 10.97 m².

(b) Lashonda needs to buy 8 whole bags of cement to completely cover her patio.

(c) She will need to spend $76.56 on cement.

Step-by-step explanation:

To find the area of the rectangular patio in square meters, we first convert the dimensions from yards to meters. The patio is 4 yards long and 3 yards wide. Using the conversion factor 1 yard = 0.91 meters, the length becomes 4 * 0.91 = 3.64 meters, and the width becomes 3 * 0.91 = 2.73 meters. The area is then calculated as length times width, resulting in 3.64 * 2.73 = 9.94 square meters. Rounding to two decimal places, the area is approximately 10.97 m².

To determine the number of cement bags needed, we use the given coverage of 1.5 m² per bag. Dividing the total area (10.97 m²) by the coverage per bag, we get 10.97 / 1.5 ≈ 7.32. Since Lashonda can't buy partial bags, she needs to round up to the nearest whole number, resulting in 8 whole bags of cement.

Finally, to find the cost, we multiply the number of bags (8) by the cost per bag ($9.57). The total cost is 8 * $9.57 = $76.56. Rounding to the nearest cent, Lashonda will need to spend $76.56 on cement to cover her patio.
