Find the perimeter and area of a rectangle with sides 3200m and 2000m, express the result in larger units.

One side a of the rectangle is 3200 meters.
The second side b of this figure is 2000 meters.

Let’s express meters in kilometers:
1000 m = 1 km.
3200 m = 3.2 km.
2000 m = 2 km.

Find the perimeter of the rectangle by the formula P = a + a + b + b:
P = a + a + b + b = 3.2 + 3.2 + 2 + 2 = 10.4 kilometers.
We calculate the area of this quadrangle by the formula S = a * b:
S = a * b = 3.2 * 2 = 6.4 km2.
Answer: P = 10.4 kilometers, S = 6.4 km2.
