Calculated the area of the rectangular triangle, one catat of which has a length of 16 cm

Calculated the area of the rectangular triangle, one catat of which has a length of 16 cm, and the second one-in 10 times shorter.

1) Since the second catt is 10 times shorter, then to find the second catat you need to divide the first category to 10:
16: 10 = 1.6 (see);
2) The area of the rectangular triangle is equal to half the work of its cathets. Then:
16 * 1.6: 2 = 8 * 1,6 = 12.8 (sq. M. See)
Answer: 12.8 square meters. cm.
