Question

a school yard has an area of 24 square meters. what shape could represent the school yard?
key: one unit square = 1 square meter

Explanation:

Step1: Analizar cada rectángulo

Primero, calculamos el área de cada rectángulo contando los cuadrados unitarios.

  • Rectángulo superior izquierdo: $3 \times 9 = 27$ (no, 3 columnas, 9 filas? Espera, mejor contar: cada cuadrado es 1. Vamos a ver las dimensiones.
  • Rectángulo superior derecho: $4 \times 5 = 20$? No, 4 columnas, 5 filas: $4\times5 = 20$.
  • Rectángulo inferior izquierdo: $3 \times 6 = 18$? No, 3 columnas, 6 filas: $3\times6 = 18$.
  • Rectángulo inferior derecho: $3 \times 8 = 24$? Espera, 3 columnas, 8 filas: $3\times8 = 24$. Otra opción: el rectángulo superior izquierdo: 3 columnas, 9 filas? No, 3x9=27. Wait, maybe the first left top: 3 columns, 9 rows? No, let's check again. Wait the problem says the school yard has area 24. Let's calculate each:
  1. Top right: 4 columns, 5 rows: $4\times5 = 20$ (no).
  2. Top left: 3 columns, 9 rows: $3\times9 = 27$ (no).
  3. Bottom left: 3 columns, 6 rows: $3\times6 = 18$ (no).
  4. Bottom right: 3 columns, 8 rows: $3\times8 = 24$ (yes). Or maybe the first left (top left) is 3x8? Wait, maybe I miscounted. Wait the key is one unit square = 1 m². So we need a rectangle with area 24. Let's find length and width such that length × width = 24. Possible factor pairs: 3×8=24, 4×6=24, 2×12=24, etc.

Looking at the rectangles:

  • Top right: 4 columns, 5 rows: 4×5=20 (no).
  • Top left: 3 columns, 9 rows: 3×9=27 (no).
  • Bottom left: 3 columns, 6 rows: 3×6=18 (no).
  • Bottom right: 3 columns, 8 rows: 3×8=24 (yes). Or the top left: 3 columns, 8 rows? Wait maybe the top left is 3x8? Wait the image: top left rectangle: 3 columns, 8 rows? Let's count the squares. If each square is 1, then 3 columns and 8 rows: 3×8=24. Wait maybe I made a mistake earlier. Let's re-express:

Wait the problem is to find which shape (rectangle) has area 24. So we need to find the rectangle with length × width = 24. Let's check each:

  1. Top right: 4 columns, 5 rows: 4×5=20 → no.
  2. Top left: 3 columns, 9 rows: 3×9=27 → no.
  3. Bottom left: 3 columns, 6 rows: 3×6=18 → no.
  4. Bottom right: 3 columns, 8 rows: 3×8=24 → yes. Or maybe the top left is 3×8? Wait maybe the first left (top left) is 3 columns and 8 rows. Let's see: if the top left has 3 columns and 8 rows, then 3×8=24. Maybe I miscounted the rows. Let's assume that the correct rectangle is the one with dimensions 3×8 or 4×6. Wait another rectangle: maybe the bottom right has 3 columns and 8 rows (3×8=24) or the top left has 3×8. Wait the problem's image: let's describe the rectangles:
  • Top right: 4 columns, 5 rows (4×5=20)
  • Top left: 3 columns, 9 rows (3×9=27)
  • Bottom left: 3 columns, 6 rows (3×6=18)
  • Bottom right: 3 columns, 8 rows (3×8=24)

So the bottom right rectangle (or maybe the top left if I miscounted rows) has area 24. Wait maybe the top left is 3×8. Let's confirm: 3 columns, 8 rows: 3×8=24. So the rectangle with 3 columns and 8 rows (or 8 rows and 3 columns) has area 24, which matches the school yard's area.

Step2: Identificar el rectángulo correcto

El rectángulo que tiene área 24 es el que tiene dimensiones tales que su producto de largo por ancho es 24. Entre las opciones, el rectángulo con 3 columnas y 8 filas (o viceversa) tiene área 24. Entonces, el rectángulo que representa el patio escolar es el que tiene 3×8=24, que es el rectángulo inferior derecho (o superior izquierdo si las filas son 8).

Answer:

El rectángulo con área 24 (por ejemplo, el de 3 columnas y 8 filas, generalmente el inferior derecho o superior izquierdo si se cuenta correctamente) es el que representa el patio escolar. (Dependiendo de la imagen, el rectángulo con 3×8=24, es decir, el que tiene 3 columnas y 8 filas de cuadrados unitarios.)
