Hello!
The ratio from millimeters to meters is 1000:1
Therefore we can exchange the length and wide into 1.2 meters and 0.9 meters.
Rectangle area =ab
a=1.2
b=0.9
Rectangle area=1.08
Have a great day!

Option 3
Step-by-step explanation:
By applying Pythagoras theorem in the given triangle,
(Hypotenuse)² = (Leg 1)² + (Leg 2)²
x² = (9.5)² + (10.5)²
x² = 200.5
x = √(200.5)
x = 14.16
x ≈ 14.2
Therefore, measure of the unknown side is 14.2 in.
Option (3) will be the correct option.
