It depends on how much they pay them per chore

The way to find the area of a triangle is A=

if the base is 3 feet longer then the height we can write it like this B=H+3
now we can add it to our area equation
20=

20=

40=

+3H
10

=

h=3.2ft
Just multiply the top number by the top number and the bottom numbers by the bottom numbers so
2/4 times 1/3=(2 times 1)/(4 times 3)=2/12
so to simplify, we find the ones exg 4/8=1/2 because 1/2 times 4/4=4/8 and 4/4 cancels out so
2/12=2/2 times 1/6
=1/6
