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? 13.8 %
No.
First, figure the total square feet (40 * 70 = ?).
Then figure the square feet in the sandbox.
Subtract the sandbox area from the total area.
Divide the smaller area by the larger area.
Now what do you get?
76.78%?
Nope.
What's the area of the whole piece of land?
What's the area of the sandbox?
0.987% 0.99%
You forgot to multiply the decimal answer by 100.
It's 98.7%.
In other words, nearly all of the piece of land is covered by grass.
To find out what percent of the land is covered by grass, we need to first calculate the area of the entire land and then subtract the area of the sandbox.
The area of a rectangle can be calculated by multiplying its length and width.
The area of the entire land is 40ft x 70ft = 2800 square feet.
The area of a square can be calculated by multiplying its side length by itself.
The area of the sandbox is 6ft x 6ft = 36 square feet.
To find the area covered by grass, we subtract the area of the sandbox from the area of the entire land:
2800 square feet - 36 square feet = 2764 square feet.
Now, to find the percentage, we divide the area of grass by the area of the entire land and multiply by 100:
(2764 square feet / 2800 square feet) * 100 = 98.71%.
Rounded to the nearest tenth of a percent, the percentage of the land covered by grass is 98.7%.
