A city plans to plant grass seed in a public playground that has the shape of a triangle with a height of H = 50 m and a base of B = 24 m. Each bag of grass seed will seed
120 m2.
How many bags of seed should be purchased?
You should use the following formula:
(Base*Height)/2=Area
(24*50)/2 = Area
Part B: The city plans to cover the park with grass. One square of grass covers 60 square feet. How many squares of grass will need to be ordered to fill the entire park?
21 squares
20 squares
19 squares
18 squares
18
To find out how many bags of grass seed should be purchased, we need to calculate the area of the playground and then divide it by the area that can be seeded with one bag of grass seed.
1. Calculate the area of the triangle:
The area of a triangle can be calculated using the formula: A = (1/2) * base * height.
In this case, the base (B) of the triangle is 24 m and the height (H) is 50 m.
So the area is: A = (1/2) * 24 * 50 = 600 m².
2. Calculate the number of bags needed:
Since each bag of grass seed can seed 120 m², we divide the area of the playground by the area per bag.
Number of bags = Area of playground / Area per bag.
Number of bags = 600 m² / 120 m² = 5 bags.
Therefore, the city should purchase 5 bags of grass seed to cover the entire public playground.
