Question

Loto begins at his back door and walks 8 yards east, 6 yards north, 12 yards east and 5 yards north to the barn door. About how many yards less would he walk if he could walk directly from the back door to the barn door

Answer 1

Below

Explanation:

SO Loto walked ( 6+5) = 11 N and (8+12) = 20 E (yards)

You can now use Pythagorean Theorem ( or 'distance' formula)

d =distance

d^2 = 11^2 + 20^2

d^2 = 121 + 400

d^2 = 521

d = sqrt (521) =22.8 yards
