Answer:
3 bags are needed to cover this flower bed
Step-by-step explanation:
Use conversion:
1 yard = 3 feet
Area of a triangle(A) is given by:
[tex]A = \frac{1}{2}bh[/tex]
where,
b is the base and h is the height of the triangle.
As per the statement:
From the given diagram:
Base(b) = 3 yards = 9 feet
Height(h) = 2 yard = 6 feet
then;
[tex]A = \frac{1}{2} \cdot 6 \cdot 9 = 3 \cdot 9 = 27[/tex] square feet.
Since, it is given that if one bag of topsoil covers 10 square feet
⇒10 square feet = 1 bag
then\;
in 27 square feet = [tex]\frac{27}{10} = 2.7 \approx 3[/tex] bag
Therefore, 3 bags are needed to cover this flower bed
