The figure shown is a square with all sides equal. Write an equation that can be used to find the value of x.

After you have written your equation, solve for the value of x. When you are ready to submit your answer, click the RIGHT ARROW to go to the next slide.

Fill in the Blanks

What is the value of x from the equation you wrote on the previous slide?

Type ONLY the number (so if the solution is x = 2, type 2)

Now that you know the value of x is equal to 4, use this value of x to find the length of each side.

You can use either side length's expression to do so. In this case, we know that x = 4 is the solution, but when working on your own, it is best to check BOTH expressions as a CHECK.

When you have found your answer, click the RIGHT arrow to submit your answer.

What is the length of each side of the square?

Remember, x = 4.

Type ONLY the number (so if the answer is 2 units, type 2)

Now that we know the length of each side is 18 units, we can now find the perimeter of the square! Remember, perimeter is the total distance around the outside of the square.

When you have found your answer, click the RIGHT arrow to submit your answer.

What is the perimeter of the square?

Remember, each side length is 18 units.

Type ONLY the number (so if the answer is 2 units, type 2)

Now it's your turn to try, but this time with an equilateral triangle!

Write and solve an equation to find the value of x. This value of x will be used in the next question, so be sure to double check it!

Type ONLY the number (so if the solution is x = 2, type 2)

Fill in the Blanks

What is the length of each side of the triangle?

Remember, x = 10.

Type ONLY the number (so if the answer is 2 units, type 2)

Fill in the Blanks

What is the perimeter of the triangle?

Remember, each side length is 35 units.

Type ONLY the number (so if the answer is 2 units, type 2)

Now try one more! This time, you will not be checked along the way! Complete all the steps like you did before and input your final answer.

You will have 5 minutes to complete the problem.

What is the perimeter of the regular pentagon (all five sides are of equal length)?

Type ONLY the number (so if the answer is 2 units, type 2)
