Answer 1

Answer: 4 cm

Explanation:

Trapezoid perimeter = Add all sides

Trapezoid perimeter = 1 + 1 + 1 + 1 = 4

Trapezoid perimeter = 4

Answer 2

The ruler measures length as 0.9 cm and 1.2cm

Now, perimeter of this parallelogram is 2X sum of its adjacent side

i.e, 2(0.9cm+1.2cm)= 2×2.1cm =4.2cm
