Question

The students found that on average 0.6 dandelion plants were present per m^2. The school field they were investigating is 150 m by 80 m. Calculate an estimate for how many dandelion plants are present on the school field.

a) 7,200 dandelion plants
b) 9,600 dandelion plants
c) 12,000 dandelion plants
d) 14,400 dandelion plants

Answer 1

The estimated number of dandelion plants on the school field is 7,200, calculated by multiplying the area of the field (12,000 m^2) by the average number of dandelions per square meter (0.6).

Step-by-step explanation:

To estimate the number of dandelion plants present on the school field, we need to calculate the area of the field and then multiply it by the average number of dandelions per square meter.

The area of the school field is calculated by multiplying its length by its width:

Area = Length × Width = 150 m × 80 m = 12,000 m2

Now, we use the average number of dandelions per square meter to estimate the total number:

Total dandelions = Area × Average number of dandelions per m2 = 12,000 m2 × 0.6 dandelions/m2 = 7,200 dandelions

Therefore, the estimate for the number of dandelion plants present on the school field is 7,200 dandelion plants.
