I would believe that the answer is 20,00 because i like to use the saying 5 or above give it a shove, for or less let it rest. So you use this saying for the number behind the number it says to round to. Which in this case is 4 so because according to the saying it says let it rest if the number is 4 or less. So that is how i got my answer :D Hope you understand now!!!

The perimeters of two opposite triangular faces includes all 4 slant edges and 2 of 4 base edges. The other two base edges are half the base perimeter, so the total length of all edges is
.. 2*(27.5 cm) +(1/2)*(30 cm) = 70 cm
What type of shape is it, are any other angles given?
