Question

How many bags of topsoil does Betsy need to cover her flower bed?

Answer 1

3 bags of topsoil is needed

Explanation:

base = 20m

height = 6 m

Area of flower bed =
`(1)/(2)*base*height\\`

`= (1)/(2)*20*6\\\\= 10*6\\= 60 square feet`

Number of bags= Total area of flower bed ÷ 20

= 60 ÷ 20

= 3
