The document provides examples of word problems involving squares, roots, triangles, speed of sound, and assignments. It includes problems about relating the amount of paint needed to cover an area, finding the side length of the largest square paint will cover, determining if a square picture will fit in a rectangular frame, calculating the side length of a square rug that covers part of a living room floor, finding the length of the legs of an isosceles right triangle given the hypotenuse, and calculating the difference in speed of sound on days with different temperatures. The document also lists math assignment questions and extra practice problems.

2. Squares, Roots and Word Problems
Example
If 5 Litres of paint will cover 18 m2, and you're painting a square
pattern, what is the side length of the largest square the paint will
cover?
Example
You have a rectangular frame that is 40 cm by 60 cm, can you
put a square picture that has an area of 800 cm2 completely
inside the frame?

Daniel's rectangular living room is 12 m by 5.5 m. He has a
square rug that covers 3/7 the area of the floor. What is the side
length of the square rug?
The hypotenuse of an isosceles right angle triangle has a length of
30 m, find the length of the other two legs of the triangle.
