Answer 2

Length of a Rectangle: 45 mm + 70 mm

To find the length of a rectangle when given two measurements, you simply add the two measurements together. In this case, the length of the rectangle is 45 mm + 70 mm.

Therefore, the total length of the rectangle is 115 mm.

Width of a Rectangle: 20 mm + 50 cm

To find the width of a rectangle when given two measurements, you need to convert the measurements to the same unit before adding them together. In this case, we have 20 mm and 50 cm.

To convert centimeters to millimeters, we multiply by 10. Therefore, 50 cm is equal to 500 mm.

Now we can add the two measurements together: 20 mm + 500 mm = 520 mm.

Therefore, the total width of the rectangle is 520 mm.

Note: It's important to ensure that the units are consistent when performing calculations.
