Answer:
60m
Explanation:
4×6=24 so you have that first chunk of the left side.
since 12-4= 8 you can tell that the bottom of the "triangle" is 8m
3x8÷2=12 so now youhave one part left.
since we have already inferred that the base of the triangle was 8m we know that the length of the rectangle was 8m. 8×3=24
now you add the three values. 24+12+24=60
