The first one is 0.27, Second one is 0.12, third one is 2 times people live per year, and the last one is 0.02
ANSWER
The exact value is 24√3
The approximate value is 41.6 to the nearest tenth.
x=52.1 units.
EXPLANATION
Let the blue dotted line be h units.
This line is opposite to the 60° angle.
The side length of the triangle which is 24 units is adjacent to the 60° angle.
So we use the tangent ratio,




This is the exact value.

This is that approximate value to the nearest tenth.
To find the side length , x, we need to use the second triangle.




Perimeter= 53+54+97= 204 yds
Area= 50x53x.5= 1325sq yds
