one bag of topsoil covers 20 square meters.

how many bags of topsoil does betsy need to cover her flower bed?

a 2 bags
b 3 bags
c 4 bags
d 5 bags

Option B. 3 bags

Step-by-step explanation:

step 1

Find the area of the flower bed

The area of the flower bed is the area of a triangle

A=(1/2)bh=(1/2)(20)(6)=60 m^2

step 2

Divide the area by 20 square meters to find the number of bags of topsoil

(60)/(20)=3 bags

step-by-step explanation:

given perimeter: 28cm

length: 9cm

atp,

2(l+w)=p of the reactangle

2(9+x)=28

18+2x=28

2x=28-18

x=10/2

x=5

therefore width is 5 cm
