To find the area of each shape, we count the number of gray squares in that shape. The key tells us that 1 square equals $1 \text{ ft}^2$. So, if a shape has 5 squares, its area is $5 \text{ ft}^2$.
Here is the step-by-step count for each problem:
Row 1:
1) Count the squares: There are
4 squares.
Area =
4 $\text{ft}^2$
2) Count the squares: There are
3 squares.
Area =
3 $\text{ft}^2$
3) Count the squares: There are
7 squares.
Area =
7 $\text{ft}^2$
Row 2:
4) Count the squares: There are
8 squares (4 on top, 4 on bottom).
Area =
8 $\text{ft}^2$
5) Count the squares: There are
6 squares.
Area =
6 $\text{ft}^2$
6) Count the squares: There are
6 squares.
Area =
6 $\text{ft}^2$
Row 3:
7) Count the squares: There are
5 squares.
Area =
5 $\text{ft}^2$
8) Count the squares: There are
9 squares.
Area =
9 $\text{ft}^2$
9) Count the squares: There are
6 squares.
Area =
6 $\text{ft}^2$
Row 4:
10) Count the squares: There are
8 squares.
Area =
8 $\text{ft}^2$
11) Count the squares: There are
9 squares.
Area =
9 $\text{ft}^2$
12) Count the squares: There are
5 squares.
Area =
5 $\text{ft}^2$
Row 5:
13) Count the squares: There are
7 squares.
Area =
7 $\text{ft}^2$
14) Count the squares: There are
7 squares.
Area =
7 $\text{ft}^2$
15) Count the squares: There are
4 squares.
Area =
4 $\text{ft}^2$
Final Answer:
1) 4
2) 3
3) 7
4) 8
5) 6
6) 6
7) 5
8) 9
9) 6
10) 8
11) 9
12) 5
13) 7
14) 7
15) 4
