Question

Длина 1) 2дм 2) ? 3) 12см 4) 25см ширина 5см 8см 5см 2смпериметр ? 36см ? ? площадь ? ? 60см" 50см"

Answer 1

P=36см
ширина а=8см
длина b=10cm ;2)?
a=8;b=10

S=60см2
a=12см;b=5см
S1=50см²
a1=25см;b1=5см

Answer 2

Let's calculate the missing values step by step:

1. Length: 2 dm = 20 cm Width: 5 cm Perimeter: 2 * (Length + Width) = 2 * (20 cm + 5 cm) = 2 * 25 cm = 50 cm Area: Length * Width = 20 cm * 5 cm = 100 cm²

2. Since only the width (8 cm) is given, we cannot calculate the length, perimeter, or area without more information.

3. Length: 12 cm Width: 5 cm Perimeter: 2 * (Length + Width) = 2 * (12 cm + 5 cm) = 2 * 17 cm = 34 cm Area: Length * Width = 12 cm * 5 cm = 60 cm²

4. Length: 25 cm Width: 2 cm Perimeter: 2 * (Length + Width) = 2 * (25 cm + 2 cm) = 2 * 27 cm = 54 cm Area: Length * Width = 25 cm * 2 cm = 50 cm²

5. Length: 60 cm Width: 50 cm Perimeter: 2 * (Length + Width) = 2 * (60 cm + 50 cm) = 2 * 110 cm = 220 cm Area: Length * Width = 60 cm * 50 cm = 3000 cm²

Please note that for the second scenario (question 2), we need more information about either the length or the perimeter or the area to calculate the missing values.
