Tom is buying topsoil for the flower bed shown below. One bag of topsoil covers 15 square meters. How many bags of topsoil does Tom need to cover his flower bed?

We need 4 topsoils

Step-by-step explanation:

I think your question is missed of key information that is the area of the flower bed, allow me to add in and hope it will fit the original one.  

Please have a look at the attached photo.

The flower bed is a triangle with its height is 5 cm and the base length is 12 cm, so we need to find out the area of it:

So the bags of topsoil does Tom need to cover his flower bed is:

= = 4

We need 4 topsoils

Step-by-step explanation:

Given:

Base, b = 15 m

Height, h = 4 m

Area of a triangle, A = 1/2 × b × h

Inputting values,

= 1/2 × 15 × 4

= 30 m^2

Since 1 bag of Topsoil = 15 m^2

Therefore, with 30 m^2 of flower bed.

1 bag of Topsoil/15 m^2 × 30 m^2

= 2 bags of Topsoil.

sry but any answer choices

not only in mathematics, scientific proof also are required in the other field of science. also maths proofs are of particular structure, containing steps and logics. so proving is like doing science, it is science. that's why it is important to prove. 

an inaccurate proof leads to errors, or stating results that are not accurate.  which wil mess the probelm up you dont want this
