To find the area of each shape, we simply count how many small squares are inside it. The key tells us that one small square equals 1 square inch ($1 \text{ in}^2$).
Let's go through them one by one:
1) This is a rectangle.
- Count the squares across: 5
- Count the squares down: 3
- Total: $5 \times 3 = 15$ squares.
- Area =
15 sq in
2) This is a tall rectangle.
- Count the squares across: 5
- Count the squares down: 8
- Total: $5 \times 8 = 40$ squares.
- Area =
40 sq in
3) This is a square.
- Count the squares across: 4
- Count the squares down: 4
- Total: $4 \times 4 = 16$ squares.
- Area =
16 sq in
4) This is a rectangle.
- Count the squares across: 5
- Count the squares down: 6
- Total: $5 \times 6 = 30$ squares.
- Area =
30 sq in
5) This is a rectangle.
- Count the squares across: 6
- Count the squares down: 4
- Total: $6 \times 4 = 24$ squares.
- Area =
24 sq in
6) This is a rectangle.
- Count the squares across: 5
- Count the squares down: 5
- Total: $5 \times 5 = 25$ squares.
- Area =
25 sq in
7) This is a tall rectangle.
- Count the squares across: 4
- Count the squares down: 7
- Total: $4 \times 7 = 28$ squares.
- Area =
28 sq in
8) This is a short rectangle.
- Count the squares across: 6
- Count the squares down: 3
- Total: $6 \times 3 = 18$ squares.
- Area =
18 sq in
9) This is a rectangle.
- Count the squares across: 6
- Count the squares down: 5
- Total: $6 \times 5 = 30$ squares.
- Area =
30 sq in
10) This is a very short rectangle.
- Count the squares across: 7
- Count the squares down: 2
- Total: $7 \times 2 = 14$ squares.
- Area =
14 sq in
11) This is a large square.
- Count the squares across: 7
- Count the squares down: 7
- Total: $7 \times 7 = 49$ squares.
- Area =
49 sq in
12) This is a tall rectangle.
- Count the squares across: 4
- Count the squares down: 6
- Total: $4 \times 6 = 24$ squares.
- Area =
24 sq in
Final Answer:
1) 15 sq in
2) 40 sq in
3) 16 sq in
4) 30 sq in
5) 24 sq in
6) 25 sq in
7) 28 sq in
8) 18 sq in
9) 30 sq in
10) 14 sq in
11) 49 sq in
12) 24 sq in
