A windowpane is 28 centimeters by 96 centimeters. What is the distance between opposite corners of the windowpane? ( In cm)
melisa1 [442]

Answer:

100 cm

Step-by-step explanation:

Using the Pythagore theorem :

Imagine that your window is a triangle, and that the distance you search is AC

So you have :

AC² = AB² + BC²

AC² = 28² + 96²

AC² = 784 + 9216

AC² = 10000

AC = √10000

AC = 100
