Answer:
238 cm
Step-by-step explanation:
so we have a scale factor of 17: 1
originally we had the dimensions: 3cm by 4m
now we have 3*17 by 4*17 = 51 cm by 68 cm
Perimeter = 2*51 + 2*68 = 238 cm
100,1000,10,000 is the correct answer or maybe 0
do parentheses first which gives you 42-4+111 then aubtract to get 38+111 which equals 149
The missing angle is 49 :)
