One side of the rectangle is 17cm 4mm, the other is 12cm 6mm larger, find the area of the rectangle.

1. Let’s find out the length of the second side of the rectangle, if it is 12 cm 6 mm longer than the first:
12 cm 6 mm + 17 cm 4 mm = 30 cm.
2. We express the first side of the rectangle in centimeters, we get:
17 cm 4 mm = 17.4 cm.
3. Determine the area by multiplying one side by the value of the other:
17.4 * 30 = 522 cm2.
Answer: the rectangle has an area of 522 cm2.
