Answer:
If each person earns $30, and they split the earnings evenly, then their total amount made would have been $<em><u>120</u></em>. This is because 30(4) = 120. Hope this helps!
To calculate the area of triangle with three sides we use Heron's formula,
Area=sqrt(s(s-a)(s-b)(s-c))
where:
s=(a+b+c)/2
thus,
s=(15+10+20)/2
=22.5
hence the area will be:
Area=sqrt(22.5(22.5-15)(22.5-10)(22.5-20))
Area=sqrt(22.5*7.5*12.5*2.5)
=sqrt5273.4375
=72.62 mm^2
