What is the length of a segment with endpoints at F(2, 11) and G(5, 16)? Round to the nearest whole number.

Answer 1

the length = the square root of the sum of the squares of the differences in the x & y coordinates

L = sqr ( (16-11)^2 + (5-2)^2)

L = sqr (5^2 + 3^2)

L = sqr (25+9)

L = sqr(34)

L = almost 5.9

You knew 6x6 =36, so the square root of 34 or 35 would be slightly less than 6
