Answer 1

Respuesta:

1) 56$u^{2}$

2) 36$u^{2}$

3) 100$u^{2}$

4) 96$u^{2}$

Explicación paso a paso:

1) As = At - A1 - A2 - A3

A1 = $\frac{8x8}{2}=\frac{64}{2}=32$

A2 = $\frac{9x5}{2}=\frac{45}{2}=22,5$

A3 = $\frac{17x3}{2}=\frac{51}{2}=25,5$

At = 17 x 8 = 136

As = 136 - 32 - 22,5 - 25,5 = 56

2)

As = At - A1

At = (18x7)/2 = 126/2 = 63

A1 = (18x3)/2 = 54/2 = 27

As = 63 - 27 = 36

3)

As = At - A1 - A2 - A3

At = $\frac{(14+6)16}{2}$ = 20 x 8 = 160

A1 = (10x4)/2 =40/2 = 20

A2 = 4 x 4 = 16

A3 = (12x4)/2 = 48/2 = 24

As = 160 - 20 - 16 - 24 = 100

4)

As = At - A1 - A2

At = $\frac{(16+8)x11}{2}=\frac{24x11}{2}=\frac{264}{2}=132$

A1 = (8x5)/2 = 40/2 = 20

A2 = (16x2)/2 = 32/2 = 16

As = 132 - 20 - 16 = 96
