I just multiply the original area by 3 right??

hmmm, im not sure if that is quite correct. personally i would find the sides of the octagon from the area equation and then redo the problem. Area of a octagon = side^2(2+2(sqrt(2))) 35cm^2=side^2(2+2(sqrt(2)) 35/(2+2(sqrt2)=side^2 7.25=side^2 sqrt(7.25)=side=2.69

i would then multiply each side by 3 and plug that into the equation: 2.69*3=8.07 area=side^2(2+(2sqrt(2)) area=8.07^2(2+(2sqrt(2) area=315cm^2

Why multiply by 3?
anonymous
  • anonymous
because each side is 3 times as long

ohhhh

so that is why cant multiply the total area by 3, because it says that each side is 3times as long, not the total area is 3times as big
