Answer:
990 square feet
Step-by-step explanation:
To find the total area of the field, we find the area of each plot first, and then multiply it by nine (representing the 9 workers)
Each plot measures 11 feet by 10 feet. Hence, they are rectangular plots.
The area of the plot is:
A = L * B
A = 11 * 10 = 110 square feet
Therefore, the area of the 9 plots is:
9 * 110 = 990 square feet
The area of the field is 990 square feet
Answer:
<h2>
first piece: 5 in</h2><h2>
second piece: 10 in</h2><h2>
third piece: 32 in </h2>
Step-by-step explanation:
x - the length of the <u>first piec</u>e
2x - twice the length of the first piece (the length of the <u>second piece</u>)
6x - six times the length of the first piece
two inches more:
6x+2 - the length of the <u>third piec</u>e
first + second + third = 47 in {total length of the pieces of steel}
x + 2x + 6x + 2 = 47
9x + 2 = 47
9x = 45
x = 45:9
x = 5 in
first piece: 5 in
second piece: 2×5 = 10 in
third piece: 6×5 + 2 = 30 + 2 = 32 in
