202.5m

Step-by-step explanation:

surface area of triangle= 1/2*b*h

=1/2*5*8=20m2

there are two triangles so 20*2=40m2

rectangle(base)=l*b

16.5*5=82.5m2

recatnagle (side)= l-b

=10*8=80m2

total surface area = 40+82.5+80=202.5m2

$53.50

step-by-step explanation:

you have to subtract the amount of money chuck earned ($72.50) by the cost of the gas for the mower ($11.25) and the new string for the trimmer he bought ($7.75).

72.50-11.25=61.25

and then subtract $61.25 by the second thing he bought (the new string for the trimmer)

61.25-7.75=53.5

so in total it's $53.50 (53 dollars and 50 cents)

0.6, 3/5, and 6% are the 3 same portion.

but, when they're all changed to a decimal they would equal to 0.6.

hope this , good luck!
