To find m we add the dimensions and equalise it to the answer first:
5m + 8 + 5m + 8 + 3m + 2 + 3m + 2 = 74 + 7m
Now we simplify
16m + 20 = 74 + 7m
Minus 20 from both sides
16m = 54 + 7m
Minus 7m from both sides
9m = 54
Divide by 9 from both sides
M=6
Plz give me brainliest answer and hope it helps!
