Answer 2

Given :

•The Distance between AB=12cm

•The Distance between BC=16cm

To Find :

•The distance between AC=?

Formula :

By using Pythagoras theorem :

$\red\bigstar\boxed{\bf{(AC)^{2}=(AB)^{2}+(BC)^{2} }}$

Solution :

• Let the distance between AB=12 cm

• Let the distance between BC=16 cm

By using Pythagoras theorem :

$\implies\sf{(AC)^{2}=(AB)^{2}+(BC)^{2}}$

$\\ \implies\sf{(AC)^{2}=(12)^{2}+(16)^{2}}$

$\\ \implies\sf{AC=\sqrt{400}}$

$\\ \implies\boxed{\bf{AC=20 cm}}$

Therefore, the distance between AC is 20 cm
