Explanation:
1. Find the area of these numbers:
(2x1.5)x2
3x2=6m
2. Find the area of these numbers:
(3x5)x2
15X2=30m
3. Find the area of these numbers:
(4x3)x2
12x2=24m
4. Add the area's you got:
30+24+6=66m
Your answer should be 66m. I may be wrong about the unit but at least I solved the surface area.
