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
