4 math on the spot a tile company tiles a wall using square tiles. a mural is painted in the center. the drawing shows the design. the area of each tile used is 1 square foot.
write a problem that can be solved by using the drawing. then solve your problem.

Explanation:

Step1: Determine total number of rows

He has 3 rows and will have 2 more rows, so total rows $=3 + 2=5$ rows.

Step2: Identify number of units in each row

There are 5 unit - squares in each row.

Step3: Use multiplication formula for area

The area $A$ of a rectangle (formed by unit - squares) is given by $A=\text{number of rows}\times\text{number of unit - squares in each row}$. So $A = 5\times5=25$ square inches.

For problem 2:

Step1: Count rows and columns

There are 3 rows and 8 columns of unit - squares.

Step2: Repeated addition

$8 + 8+8=24$.

Step3: Multiplication

$3\times8 = 24$ square feet. Area $=24$ square feet.

For problem 3:

Step1: Count rows and columns

There are 4 rows and 3 columns of unit - squares.

Step2: Repeated addition

$3+3 + 3+3=12$.

Step3: Multiplication

$4\times3=12$ square inches. Area $=12$ square inches.

For problem 4:
Let's say the problem is: "What is the area of the non - mural part of the wall?"

Step1: Count total tiles

Count the total number of tiles in the drawing. Let's assume there are 10 rows and 6 columns of tiles, so total tiles $=10\times6 = 60$ square feet.

Step2: Count mural tiles

Let's say the mural part has 4 rows and 3 columns of tiles within it, so mural area $=4\times3=12$ square feet.

Step3: Calculate non - mural area

Non - mural area $=60 - 12=48$ square feet.

Answer:

1. The area of the picture is 25 square inches.
2. Add: $8 + 8+8=24$, Multiply: $3\times8 = 24$, Area $=24$ square feet.
3. Add: $3+3 + 3+3=12$, Multiply: $4\times3=12$, Area $=12$ square inches.
4. Problem: What is the area of the non - mural part of the wall? Answer: 48 square feet.
