The length of Peter's rectangular living room is 6 meters and the distance between opposite corners is 7 meters. What is the width of Peter's living room? If necessary, round to the nearest tenth.

Answer 1

3.6 m

Explanation:

Given that :

Length of room = 6

Distance between opposite corners = 7

Width of room :

Using Pythagoras rule:

Opposite ²= hypotenus² + adjacent²

From. The diagram attached :

w² = 7² - 6²

w² = 49 - 36

w² = 13

w = 3.605

w = 3.6 m
