How many bags of topsoil does Tom need to cover his flower bed?

Answer 1

Answer:

2 BEGS

Step-by-step explanation:

IF one bad of topsoil cover 15cm(square) means

area of the flower bed = 1/2 × 12 × 5 = 30cm(square)

30÷15 = 2 begs

Answer 2

Disclaimer:

One bag of topsoil covers 15 square meters.

Concept:

The area of the triangle can be calculated as,

A = 1/2 bh

where b is the base of the triangle and h is the height of the triangle.

Given:

A triangular flower bed and one bag of topsoil cover 15 square meters of area.

Find:

The number of bags required to cover the flower bed.

Solution:

The number of bags can be calculated by dividing the area of the flower bed by the area of one bag.

Area of the flower bed, A =  1/2 bh

A = (1/2) 12×5

A = (1/2) 60

A = 30 m²

As one bag covers 15 m².

For 30 m², the number of bags required,

n = Area of flower bed / Area of one bag

n = 30/15 = 2

Hence, 2 bags are required to cover the flower bed with the topsoil. Hence, the correct option is (A) 2 bags.
