Answer:
1. (3x+2)cm
2. What expression represent the perimeter? and what expression represent it's area?
3. Represent the unknown variable
-I wasn't sure, but "x" is the only variable in the expression and the “x” is the most common way of marking the unknown element/variable.
4. Formulate equation based on the condition based on the conditions
-Area of Square = side² or A=s²
-Area of Square = side² or A=s²-Perimeter = 4(side) or P=4s
5. Solve the equation
Area:
-Substitute the given
A=(3x+2cm)²
A=(3x+2)(3x+2)
I use distributive property
A=3x(3x+2)+2(3x+2)
=9x²+6x+6x+4
A=9x²+12x+4cm²
Perimeter:
P=4(3x+2cm)
P=12x+8cm
6. Answer the question being asked
-The expression that represent the perimeter of the square is 12x+8cm and the expression that represent the area is 9x²+12x+4cm²
