I think that you should imagine what regular shape the figure would have been.
The fact that two sides are 9inches makes me think it would have been a square.
The area of a square is A= l² where l is the length of one side and A=area
A=9*9
A=81 in.²
Next, find the area of the part that is taken away,(it looks like a triangle). to find that, if the figure was a square, the length on top would be 9 not 5, so the length gone is 9-5=4, so the base of the triangle is 4,
If the figure was a square, the length on the other side would be 9 not 4 so the length gone is 9-4=5, so the height of the triangle is 5
the area of a triangle is A= 1/2bh, where A is area, b is base and h is height.
A=1/2*4*5 A=10 so the area of the part gone is 10 inches²
The area of the figure is the area of the square -the area of the triangle
A=81-10
A=71inches²

Answer:
The function to represent the area a of the section inside the border is
Step-by-step explanation:
Given section inside the border is inches and
inches.
We need to write the function to represent the area of the section inside the border.
We can see the length of border is and width of the border is
.
So, the area of the rectangle will be
The area will be
So, the function to represent the area a of the section inside the border is
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.
