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!
