What is the area of this square?

a.
160 km

b.
160 km²

c.
1,600 km

d.
1,600 km²

The formula for finding area is l * w

Since a square has all sides the same length, we need to multiply 40 by 40.

40 * 40 = 1,600 ←

Check work by dividing 1,600 and 40:

1,600 ÷ 40 = 40

Your answer is Option D. 1,600 km². (The answer wouldn't be option C as it is referring to perimeter, not area)

The area of the square is 1,600 km².

I hope this helps! :)
