I need help finding the area of these two​

50 cm² and 56 cm²

Step-by-step explanation:

The area (A) is calculated as

A = × d₁ × d₂ ( d₁ and d₂ are the length of the diagonals )

(2)

A = × (8 + 2) × (5 + 5)

   = 0.5 × 10 × 10

   = 5 × 10

    = 50 cm²

(3)

A = × (12 + 2) × (4 + 4)

   = 0.5 × 14 × 8

   = 7 × 8

    = 56 cm²
