To calculate the perimeter of the given dimensions, you need to add up all the lengths of the sides:
Perimeter = (26 mm) + (48 mm) + (2.7 cm) + (3.5 cm) + (2.5 cm)
However, since the units are not the same, you need to convert all measurements to the same unit before adding them up.
1 cm = 10 mm
So, 2.7 cm = 27 mm, 3.5 cm = 35 mm, and 2.5 cm = 25 mm.
Now, the perimeter calculation becomes:
Perimeter = (26 mm) + (48 mm) + (27 mm) + (35 mm) + (25 mm)
Perimeter = 26 mm + 48 mm + 27 mm + 35 mm + 25 mm
Perimeter = 161 mm
Therefore, the perimeter of the given dimensions is 161 millimetres.
hope it helps
