There is a rectangular piece of land that measures 40ft by 70 ft in the middle there is a square sandbox that is 6 ft on each side the rest of the land is covered in grass what percent of the land is covered by grass rounded to the nearest tenth of a percent?0.98 %= 0.99%
40 x 70 = 2800 total
sandbox = 6 x 6 = 36
2800-36 = 2764 sq feet.
% = (2764/2800)*100 = 0.98714*100 = 98.714%.
To the nearest tenth would be 98.7%.
To the nearest hundredth (which you had in one of your earlier posts) is 98.71%. To the nearest thousandths it is 98.714. Check my work carefully.
thank you very much
To find the percentage of land covered by grass, we need to calculate the area of the grass and the total area of the land.
1. Calculate the area of the grass: Since the sandbox is a square with sides measuring 6 ft, the area of the sandbox can be found by multiplying the length of one side by itself: 6 ft * 6 ft = 36 sq ft.
2. Calculate the total area of the land: The rectangular piece of land measures 40 ft by 70 ft. Therefore, the total area can be found by multiplying the length by the width: 40 ft * 70 ft = 2800 sq ft.
3. Calculate the area covered by the grass as a fraction of the total area: Divide the area of the grass (36 sq ft) by the total area of the land (2800 sq ft). 36 sq ft / 2800 sq ft ≈ 0.01285714.
4. Convert the fraction to a percentage: Multiply the fraction by 100 to convert it to a percentage. 0.01285714 * 100 ≈ 1.28571428%.
5. Round the percentage to the nearest tenth: Since we need to round the percentage to the nearest tenth of a percent, the final answer is approximately 1.3%.
Therefore, approximately 1.3% of the land is covered by grass.
