Mathematics
1 answer:
S_A_V [24]3 years ago
6 0

Answer:

50 cm² and 56 cm²

Step-by-step explanation:

The area (A) is calculated as

A = \frac{1}{2} × d₁ × d₂ ( d₁ and d₂ are the length of the diagonals )

(2)

A = \frac{1}{2} × (8 + 2) × (5 + 5)

   = 0.5 × 10 × 10

   = 5 × 10

    = 50 cm²

(3)

A = \frac{1}{2} × (12 + 2) × (4 + 4)

   = 0.5 × 14 × 8

   = 7 × 8

    = 56 cm²

Consider this claim: Changes in environmental conditions always result in new ecosystems and loss of biodiversity characterized
Dafna11 [192]

Answer:

If a desert became flooded, some species would immeadiately go extinct, distrupting the ecosystem, biodiversity, and the food web. This flood might cause new species to enter the ecosystem as well, through means such as rafting. Other species would be forced to adapt to the new environment, leading to adaptation and possibly speciation. For a time the ecosystem would not be very stable, but after a relatively short time, 10 or 20 years, the ecosystem could stabilize itself. So my conclusion is that ecosystems are relatively fluid, they can adapt to almost anything if they have enough time and the change in environment isn’t too drastic.
