Square Root Word Problems Worksheets
If we remember back, a square root is a factor of a value that when it is multiplied by itself gives you the original value. This form of math is usually stated with the symbol (√ ). We can illustrate this concept by accepting that 5 x 5 = 25. With this in mind, that would mean that the square root of 25 is 5 or √25 = 5. While this type of math just feels like a fun puzzle solving activity, there are a great many uses for square roots in the real world such as architecture, engineering, and even farming. Not to mention that it is a key aspect of solving any problem that includes a right triangle to find a measure of a missing side or angle through Pythagorean Theorem. These worksheets and lessons provide practice word problems that require the use of a square root at some point in the process.

What is Square Footage?
If someone asks your age, you say "I'm 13 years old." Is that a correct use of units? You use "years old" to imply that you are thirteen years of age. Just like that, when we are talking about a large surface area, we denote these units by saying "This flat is 700 square feet."
Take your room for example. It covers up a large space in your house. The space it covers is known as surface area. Now when you measure the surface area, you will calculate it in the unit of square feet. Just like for measuring time use seconds or minutes, for surface area, the S.I unit is known as square feet. We calculate the surface areas of various shapes such as triangles, squares, rectangles and many more!
When you begin working on, just about, any construction and building project you will need to determine this measure of each room or area you are working on to determine the amount of material that you will need to complete the project. This measure also helps you determine the price of the cost of materials. Most contractors who build rooms or homes charge by this measure too. That is why tis measure warranted such a long discussion. The square footage of anything is simply the product of two measures within it: length (the longest side) and width (other side). Just multiply those values to determine the square footage.
