​

Answer 1

perimeter=52 km.

area= 160 sq. km.

Explanation:

10x2=20

16x2=32

32+20=52

10x16=160

Answer 2

16

Explanation:

The perimeter of square p = 16 cm.

Length of each side (in cm) let a = 16/4 = 4 cm.

Area of given square = a * a = 4 cm * 4 cm = 16 cm^2.

Now, m^2 = cm^2 / 100^2.

Hence Area of given square in m^2 = 16 / 10000 = 0.0016 m^2.
