Answer 1

1)

P = l + l + l + l

P = 2.5 + 2.5 + 1.7 + 1.7

P = 8.4 m

S = b × h

S = 2.5 × 1.7

S = 4.25 m²

2)

P = l + l + l

P = 8.3 + 8.3 + 8.3

P = 24.9 m

S = b × h

S = 8.3 × 7.1 / 2

S = 58.93 / 2

S = 29.465 m²

3)

P = B + b + 2l

P = 14 + 11 + 2 (6.8)

P = 14 + 11 + 13.6

P = 38.6 m

S = (B + b) / 2 × h

S = (14 + 11) / 2 × 6.6

S = 25 / 2 × 6.6

S = 82.5 m²

4)

P = l + l + l

P = 12.5 + 20 + 20

P = 52.5 m

S = b × h / 2

S = 12.5 × 18.9 / 2

S = 236.25 / 2

S = 118

5)

P = l × 5

P = 8 × 5

P = 40 m

S = P × a / 2

S = 40 × 5.5 / 2

S = 220 / 2

S = 110 m²

6)

P = l + l + l

P = 8.25 + 32.5 + 24.72

P = 65.47 m

S = b × h / 2

S = 32.5 × 2.3 / 2

S = 74.75 / 2

S = 37.375 m²

7)

P = l + l + l + l

P = 9 + 9 + 9 + 9

P = 36 m

S = b × h

S = 9 × 9

S = 81 m²

8)

P = l + l + l + l

P = 2.5 + 2.5 + 2.5 + 2.5

P = 10 m

S = D × d / 2

S = 3 × 4 / 2

S = 12 / 2

S = 6 m²
