round to the nearest tenth. a rectangular plot of land is 80 meters wide and 98 meters long. Find the length of the diagonal and if necessary, round to the nearest tenth.

Answer 1

This calls for the Pythagorean Theorem.

a^2 + b^2 = c^2

80^2 + 98^2 = c^2

6,400 + 9,604 = c^2

16,004 = c^2

126.506 = 126.5 = c
