Question

*aiuda es para mañanaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaa*

Answer 1

a) Área = (b x h)/2 = (5 x 6)/2 = 15 cm^2

b) Área = a x a = 4 x 4 = 16 cm^2

c) Área = r^2 x pi = 3^2 x pi = 9 x pi = 28,26 cm^2

d) Área = ((B + b)/2) x h = ((3 + 2)/2) x 1,5 = 3,75 cm^2

e) Área = b x h = 4 x 3 = 12 cm^2  

Answer 2

Respuesta:

15

Explicación paso a paso:

a) (bxh)/2

(5x6)/2=15cm^2

b) L^2

3^2=9cm^2

c) 3,14x3cm^2=28,26 cm^2

d) ((3cm+2cm)/2)1.5cm=2.5cmx1.5cm=3,75cm^2

e) 4cmx3cm=12cm^2
