Answer:
Step-by-step explanation:
Area = 35*100*2 + 50*100*2 + 50*35*2
= 7000 + 10000 + 3500
= 20500 cm2
1cm : 3m
to get from 12m to 3m you have to divide by 4, so if:
3 x 4 = 12
then you do the same to the 1cm and you get:
1 x 4 = 4
Therefore:
1cm : 3m
4cm : 12cm
the model is 4cm
the answer is the above in bold
hope it helped :)
