"x" (and any subsequent words) was ignored because we limit queries to 32 words.
Here are the steps I would use to complete this question.
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
Turn everything into decimal form, then divide by 2.
To turn into decimal divide the numerator by the denominator, and leave the whole number as it is.
For slide 1
45.4/2=22.6
For side 2
Gusset plate is 1....
take 5.75 and divide it by 2 =2.875
Take 3.333/2 = 1.6665
Corner of side is 1 and 1 inch thick
for side 3
37.4 divided by 2 = 18.7
