Explanation:

We first find the area of a trapezium and rectangular face

Fourmula to find the are of a trapezium is:

Area=1/2*(B+b)*h

=1/2*3.7*1.9

=3.515m²

Since every rectangular face is different we gotta find each of them

Area1=4.8*2.1

=10.08 m²

Area2=4.8*1.4=6.72m²

Area3=4.8*2.3=11.05m²

Area4=4.8*1.9=9.12m²

Now we find the area of the whole prism

Area=3.515*2+10.08+6.72+11.05+9.12

Area=44m²

Sorry my wireless went down!!!

Hope this helps and you already know what I would like to get
