grassland-29%
wilderness-9%
urban-2%
wetlands-3%
forest-30%
cropland-17%
if humans use half of forest and grassland plus all cropland and urban areas how much land is used by humans.
is it 48.5%
yes
Hey are you able to email me I have a question for you please
To calculate the amount of land used by humans, we add up the percentages of forest, grassland, cropland, and urban areas that are used by humans.
Given percentages:
- Forest: 30%
- Grassland: 29%
- Urban: 2%
- Cropland: 17%
First, we need to find half of the forest and grassland percentages:
Half of forest = (30% ÷ 2) = 15%
Half of grassland = (29% ÷ 2) = 14.5%
Now, let's calculate the total percentage of land used by humans:
Total land used by humans = Half of forest + Half of grassland + Cropland + Urban
= 15% + 14.5% + 17% + 2%
= 48.5%
So, the total land used by humans is indeed 48.5%.
