Answer:
Hey!
Your answer is 150 square meters!
Step-by-step explanation:
13*3=39 (the tilted face)
12*3=36 (the flat face)
5*3=15 (the base)
TO FIND THE TRINGLULAR AREA:
1/2 base x height...
1/2 x 5 x 12 = 30
(WE DOUBLE THIS BECAUSE THERE ARE TWO TRIANGLES)
SO 60...
ADD THESE TOGETHER...
39 + 36 + 15 + 30 + 30...
GIVES US 150 square metres
HOPE THIS HELPS!!
