Answer 1

Explicación paso a paso:

Figura 1. Trapecio.

p = B + b + L +L

p = 12 + 4 + 5.6 + 5.6

p = 27.2

a = (B + b) • h/2

a = (12 + 4) • 4/2

a = 32

Figura 2. Rombo.

p = L + L + L + L

p = 4.5 + 4.5 + 4.5 + 4.5

p = 18

a = D • d /2

a = 8 • 4 /2

a = 32/2

a = 16

Figura 3. Triángulo.

p = L + L + L

p = 4 + 8.9 + 13

p = 25.9

a = b • h /2

a = 13 • 3.5 /2

a = 22.75

Figura 4. Circunferencia.

p = π • 2r

p = 3.14 •2(4)

p = 25.12

a = π • r²

a = 3.14 • (4)²

a = 50.24
