Question

To get to his parents' house, Tommy would have to drive due north 16 kilometers. To get to his grandparents' house, he would have to drive due east 12 kilometers. What is the straight-line distance between the parents' and grandparents' houses?

Answer 1

By Pythagoras theorem

you will get this--

required distance=

${16}^{2} + {12}^{2} = {20}^{2}$

so required distance is 20 kilometres

Answer 2

Answer:

20 km

Step-by-step explanation:

Put it into a right angled triangle- you are finding the hypotenuse.

Use Pythagoras- 16^2 + 12^2 = Hypotenuse^2

400 = Hypotenuse^2

Hypotenuse = 20km

Therefore the answer is 20km
