You used the scale factor to find the base of the smaller pyramid which was 13cm
Then you needed to find the height of the trapezium face using Pythagoras and then add up all the areas
I might attach a solution later

You can’t use 30 for the trapezium since it’s slanted. I think you need to use Pythagoras

It was a square base pyramide. And I dont know which 30 you are talking about? The lenght of the side at the bottom was 39

I mean the height- it’s slanted so you cant use 30

It was not slanted. The line for the height was straight

You can because trapezium is height not the side length

The perpendicular height of the trapezium is slanted I don’t think it’s 30.

Here’s my solution for the pentagon 6 marker (sorry if it’s confusing I kept it in exact form throughout)
