Answer:
59.25 currency ; No. of cans rounded to next whole number
Step-by-step explanation:
Draw a perpendicular line frrom the 12m. line onto the 20m. line. We get a rectangle on the left and a right-triangle on the right.
Using Pythagorous theorem,
Fence = m = 15 m
So, area of the lawn = ( 1/2 ) * ( 12 + 20 ) * 16 sqm = 240 sqm
So, number of cans needed = 240/100 = 2.4 ≈ 3 [Cause cans can't be partially bought ]
Total cost = 3 * 19.75 currency = 59.25 currency
( However, if cans can be partially bought, then total cost = 47.4 currency )
Answer:
Step-by-step explanation:
<h3> The complete exercise is attached.</h3><h3></h3>The area of a rectangle can be calculated with this formula:
Where "l" is the lenght and "w" is the width.
Then, you can notice that it can be obtained by multiplying the dimensions of the rectangle.
Knowing this, you can determine that the total area of the two flowers bed can be obtained by adding the products of their dimensions.
Since one of the rectangular flower bed is 2.78 feet by 4.81 feet and the other bed 2.78 feet by 5.61 feet, you can write the following expression to find the total area (in square feet)of the two beds:
If you factor out 2.78:
or
Therefore, the expression that does not represent the total area in square feet of the two beds, is:
16 = c8
c =
c = 2
