: David measured the floor of his storage unit, which is rectangular. It is 12 meters wide and 15 meters from one corner to opposite corner. How long is the storage unit?

9 meters

Step-by-step explanation:

A line between two opposite corners splits the floor into two right angled triangles, therefore we can use Pythagoras’ Theorem which is:

a^2 + b^2 = c^2

where c is the hypotenuse, and a and b are the other two sides.

Hypotenuse in this question is 15 metres while one side is 12 metres. The length will now be:

a^2 + b^2 = c^2

12^2 + b^2 = 15^2

b^2 = 15^2 - 12^2

b^2 = 225 - 144

b^2 = 81

b = ✓81

b = 9m

The length of the storage unit is 9m

answer: there are x+184 pages in olivia's book.

step-by-step explanation:

let the total number of pages in the book which olive has already read be x.

then if olive has 184 pages left to read, then the total number of pages are in olive's book= pages she has read+pages she has left to read

therefore, the total number of pages in olivia's book=

hence, there are x+184 pages in olivia's book.
