Answer 2

Answer:

100 (unit square)

Step-by-step explanation:

Perimeter = 40

4 x side = 40

Side = Perimeter divided by 4

       = 40/4

       = 10

Perimeter = 4 x 10 = 40

Area of a square = side x side

                            = 10 x 10

                            = 100 cm/m/mm (square)
