Question

Answer 1

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
