Question

s=0.231м^2 h=0.7м найдите a

Answer 1

$s = \frac{ah}{2} \\ 0.231 = \frac{0.7a}{2} \\ 0.462 = 0.7a \\ a = 0.462 \div 0.7 \\ a = 0.66$

Answer 2

Ответ:

s=1/2ha;a=2s/h

Пошаговое объяснение:

$a=\frac{2*0.231}{0.7}=\frac{\frac{462}{1000}}{\frac{7}{10} } =\frac{462}{1000}:\frac{7}{10} \\\frac{462}{1000}*\frac{10}{7}=\frac{66}{100}$=0.66
