Question

I need help finding the area of these two​

Answer 1

50 cm² and 56 cm²

Explanation:

The area (A) is calculated as

A =
`(1)/(2)` × d₁ × d₂ ( d₁ and d₂ are the length of the diagonals )

(2)

A =
`(1)/(2)` × (8 + 2) × (5 + 5)

= 0.5 × 10 × 10

= 5 × 10

= 50 cm²

(3)

A =
`(1)/(2)` × (12 + 2) × (4 + 4)

= 0.5 × 14 × 8

= 7 × 8

= 56 cm²
