Question

7. Calcule a área de cada triângulo ​

Answer 1

$a) \: \: a = \frac{b \times h}{2}$

$a = \frac{4.8 \times 4.2}{2}$

$a = \frac{20.16}{2}$

$a = 10.08m {}^{2}$

$b) \: \: a = \frac{4 \times 2.7}{2}$

$a = \frac{10.8}{2}$

$a = 5.4m {}^{2}$

$c) \: a = \frac{5 \times 3.3}{2}$

$a = \frac{16.5}{2}$

$a = 8.25 m{2}$
