Provided on the real test, exactly like this.
| Shape | Perimeter | Area |
|---|---|---|
| Circle | C = πd = 2πr | A = πr² |
| Triangle | P = a + b + c | A = bh ÷ 2 |
| Rectangle | P = 2(l + w) | A = lw |
| Parallelogram | P = 2(b + c) | A = bh |
| Trapezoid | P = a + b + c + d | A = (a + b) ÷ 2 × h |
| Rhombus | P = 4s | A = bh = (d₁ × d₂) ÷ 2 |
| Kite | P = 2(a + b) | A = (c × d) ÷ 2 |
| Object | Surface area | Volume |
