If you mean an isosceles trapezoid with parallel sides of 18 cm and 27 cm then the length of the 4th sides is 2 cm
If a 27 ft tall pole casts an 18 foot shadow, a 63 ft tall pole casts an x foot shadow.Put 27/18 and 63/x.Cross multiply, get 27x=1134Divide by 27 on both sides, a 63 foot tall pole casts a 42 foot long shadow.
The geometric mean of 18 and 27 is 22.045407685
It is 20 units.
The Geometric Mean of 12 and 27 is 18.0
27 cubic inches.
The length of a midsegment is half that of the parallel side of the triangle; assuming the midsegment is parallel to the [given] base, then its length is 27 ÷ 2 = 13.5 units.
The number of tiles can be expressed as [ n2 + 4n +6 ]
length x width x height= cubic feet cubic feet/27= cubic yards

n + 18 = 27 subtract 18 to 18 and 27 18-27=9 n = 9
9,18,27,36,45,54
18 out of 27 is 66.67%.
27-18=9.
examples are....a+18=27=a+18-18=27-18=9
18 + 27 = 45
