Perimeter is the distance around a shape. You add all of the lengths to get the perimeter.
3 1/10 + 4 7/20 + 5 9/10 + 4 7/20 = 17 7/10.
This could be wrong — sorry in advance if it is.
The answer to your problem is 360
24:15 would be the simplified version, if that's what you meant.
So we have lengths a and b and are given:
2a+2b = 66 => a+b = 33 => a= 33-b
a*b = 272
plug in one into the other:
(33-b)b = 272 => -b^2 +33b - 272 = 0
Can be factored as (b-16)(b-17) = 0, if you don't "see" this immediately, use the well known abc formula to find b.
So a=16 and b=17 or vice versa.
