Question

HELP ME! Find the approximate side lengths and the perimeter of triangle UVW. If necessary, round your answers to the nearest hundredth.

Answer 1

Count the number of grids for each side length.

UV = 5 units

VW = 6 units

Now, for UW use the pythagoras theorem to calculate.

$UW=\sqrt{5^2+6^2}=\sqrt{25+36}=\sqrt{61}\approx7.8$

Therefore, the perimeter is 5 + 6 + 7.8 = 18.8 units.
