There are about 7.77 giraffes per square mile
Step-by-step explanation:
The given is:
- In a certain area of the savanna that is 12 km long and 5 km wide
- There are 180 giraffes in this area
We need to find how many giraffes per square mile in this area
At first let us change the kilometer to mile
∵ 1 km = 0.621371 miles
∵ The length is 12 km and the width is 5 km
∴ 12 km = 12 × 0.621371 = 7.456452 miles
∴ 5 km = 5 × 0.621371 = 3.106855 miles
∵ The area = Length × width
∴ The area = 7.456452 × 3.106855
∴ The area = 23.16611518 miles²
∵ There are 180 giraffes in this area
- Divide the number of giraffes by the area
∵ 180 ÷ 23.16611518 = 7.769969139
∴ There are about 7.77 giraffes per square mile
There are about 7.77 giraffes per square mile
