Explanation: Hello Students, time to practice and review the steps for the problem.

Lesson Steps

Step	Type	Explanation	Answer
1	Problem	A square has an area of \$64 cm^2\$. What is the length of each side?
2	Step	The area(A) of a square is	\$36 cm^2\$
3	Step	Now we want to find the sides of a square.
4	Formula	Area of a square is	A = Side x Side
5	Step	Substitute the values	36 = s x s
6	Step	Apply square root on both sides	\$\sqrt(64) = \cancel \sqrt s^\cancel(2)\$
7	Step	The square root of 36 is	6
8	Step	After simplification,we get	s = 6

Answer

Problem

A square has an area of \$64 cm^2\$. What is the length of each side?

Step

The area(A) of a square is

\$36 cm^2\$

Step

Now we want to find the sides of a square.

Formula

Area of a square is

A = Side x Side

Step

Substitute the values

36 = s x s

Step

Apply square root on both sides

\$\sqrt(64) = \cancel \sqrt s^\cancel(2)\$

Step

The square root of 36 is

Step

After simplification,we get

s = 6

Step

The sides of a square are 6.

SumUp

Can you summarize what you’ve understood in the above steps?

Choice.A

This is correct because the square root of 36 is indeed 6.

6 cm

Choice.B

This is not correct because the square root of 36 is not 8

8 cm

Choice.C

This is not correct because the square root of 36 is not 5

5 cm

Choice.D

This is not correct because the square root of 36 is not 9

9 cm
