Answer:
Step-by-step explanation:
we are given that A vegetable garden and a surrounding as a shaped like a square that together a 11 ft wide. The path is 2 feet wide.since together the width of Vegetable garden and path is 11 ft, the width of the vegetables garden will be the difference between the total width and the width of path Thus,
simplify substraction:
recall that, every single side of a square is equal to each other therefore the the area of the garden will be
simplify square:
together the garden and path makes a square of every side length 11 ft saying that the area will be:
simplify square:
the area of path will be the difference between the total area and the garden area therefore,
simplify addition:
to figure out how many bags are needed to cover the path. we just need to divide the area of the path by the area of a bag of gravel and that yields:
simplify division:
hence,
<u>4</u> bags are needed to cover the path.
In this question, it is given that the diagonal of the board is 18 inches long and one side of the board is 12 inches long.
Let the other side is of length b inches .
Now we use pythagorean identity, which is
Here, a = 12 and c=18
Substituting these values, we will get
And the formula of perimeter is
Substituting the values of the two legs, we will get
