1/3(x)=22-x
x/3=22-x
(x/3=22-x)3
3x=66-3x
6x=66
x=11
1.q=p-2n
2.q=75000-2*20000
q=75000-40000
q=35000
3.p=90000+2*25000
p=90000+50000
p=140000
Hope this helps :)
Take 20 and divide it by 4 and you get 5mm squared .
There are four sides so take the total which is 20 mm and divide it by the sides to get one side.
