Answer 2

To perform the given arithmetic expression, we need to convert all the measurements to the same unit. Let's convert everything to centimeters (cm) and then proceed with the calculations.

1 meter (m) = 100 centimeters (cm) 1 decimeter (dm) = 10 centimeters (cm) 1 millimeter (mm) = 0.1 centimeters (cm)

Now, let's convert each value to centimeters:

2 m = 2 * 100 cm = 200 cm 35 cm = 35 cm 5 dm = 5 * 10 cm = 50 cm 6 cm = 6 cm 74 dm = 74 * 10 cm = 740 cm 95 cm = 95 cm 3 m = 3 * 100 cm = 300 cm 1 mm = 1 * 0.1 cm = 0.1 cm 8 dm = 8 * 10 cm = 80 cm 7 cm = 7 cm 3 mm = 3 * 0.1 cm = 0.3 cm

Now, let's perform the arithmetic:

2m 35cm - 5dm 6cm + 74dm - 95cm + 3m 1mm + 8dm 7cm 3mm

= 200cm + 35cm - 50cm + 6cm + 740cm - 95cm + 300cm + 0.1cm + 80cm + 7cm + 0.3cm

Now add all the values:

= 200cm + 35cm - 50cm + 6cm + 740cm - 95cm + 300cm + 0.1cm + 80cm + 7cm + 0.3cm = (200 + 35 - 50 + 6 + 740 - 95 + 300 + 0.1 + 80 + 7 + 0.3) cm = 1323.4 cm

So, the result of the expression is 1323.4 centimeters.
